I have a strange problem in edx devstack. When I am running devstack after paver command on my localhost then I am not able to get anything on the screen once the browser screen come to loading state.
Then after a lot of time nothing is being displayed on the screen and I can see some warnings in the logs which I have attached with this que.
I have commented that code which are causing the warning message.
But after commenting warnings have gone but nothing has changed the browser again goes in loading mode and nothing happens on the screen after hitting to localhost URL,it just go in to the loading mode and nothing is being displayed.
I have also tried to run the openedx in firefox but in fore fox the links and everythings are coming but they are coming with out any style and design for the edx. I have attached a screenshot for the same.
Please help me with this issue as I am not able to figure out what to do.
P.S. I have re-installed the whole stack using virtual box, but nothing has worked for me.
Thank you very much in advance.

Hi Guys after I posted on google group I finally got the answer. I feel like I should post this answer on stackoverflow so it is convenient for people who got stuck in their development.
1) From the screen shot it seems it is a permission issue. Give correct permission for edx-platform and themes folder if you are using any. Then try restarting the LMS and CMS and reload the page.
sudo chown -R edxapp:edxapp /edx/app/edxapp/edx-platform
sudo chown -R edxapp:edxapp /edx/app/edxapp/themes.
sudo /edx/bin/supervisorctl restart edxapp:
2) If you are able to load CMS page and LMS showing blank, may be mongodb is not running.
#mongo , if it shows some error check if swap size is full
# free -m
If swap is full, create new swap file, follow the instruction in the below link blindly.
http://www.cyberciti.biz/faq/linux-add-a-swap-file-howto/
Then try restarting mongodb, you can try restarting the system once.

Small question regarding how to interpret a SpringBoot Webflux app access log please.
Currently, in my logs, more precisely access logs, I can see:
2021-07-31 13:46:19.913 INFO [service,,] 10 --- [or-http-epoll-1] reactor.netty.http.server.AccessLog : ip - - [31/Jul/2021:13:46:19 +0000] "GET /health HTTP/1.1" 200 3349 6
2021-07-31 13:47:18.531 INFO [service,,] 10 --- [or-http-epoll-2] reactor.netty.http.server.AccessLog : ip - - [31/Jul/2021:13:47:18 +0000] "GET /health/liveness HTTP/2.0" 200 3312 8
2021-07-31 13:47:33.347 INFO [service,,] 10 --- [or-http-epoll-2] reactor.netty.http.server.AccessLog : ip - - [31/Jul/2021:13:47:33 +0000] "GET /health HTTP/1.1" 200 3349 11
I understand the 200 is probably my http response, I return http 200.
But I am having a hard time understanding what are the last two numbers please.
3349 6
3312 8
3349 11
Any help?
Thank you
It does depend on log format definition, but it looks like the larger number is response size in bytes and the smaller is processing time of the request in ms.
I'll look at documentation to see where I'd expect to find the log format definition for a spring webflux app. I'd expect the format to be defined in a similar way to httpd access logs ( documentation for those is at https://httpd.apache.org/docs/2.4/logs.html)
Hi I'm wodering if it is possible to get the same webrick monitoring functionality in apache2. Doing a quick reseach on this site an goolge, I found that I can use tail -f to monitor the log realtime. But the info I need is not displayed on the access.log.
On Webrick I can see the complete request that came to the server, this includes all POST parameters that are sent to it. I'm developing a Phonegap aplication that is aiming to a production server with apache, and I need to doublecheck my REST request to the server (exactly as I did in my development environment in Rails with Webrick). That's why tail -f don't fit my needs.
Does anyone has a solution?
Thanks in advance.
I've got the solution. And it's a stupid answer. I was looking to the apache2 other_vhosts_access.log file, and the info I was getting was:
migtrace.com:80 89.131.219.51 - - [16/Sep/2013:12:14:14 +0200] "POST /api/reports.json HTTP/1.1" 200 964 "-" "curl/7.29.0"
But if I tail -f the rails production.log what I get is:
Started POST "/api/reports.json" for 89.131.219.51 at 2013-09-16 12:14:14 +0200

That is exactly what I need.
I am using Red5 version 1.0.0(final release) for Java 6 on Windows XP sp3.I am using the installer version downloaded from https://code.google.com/p/red5/. I have a project wherein I am performing live webcam chats between the users. I am using RTMPT (HTTP over RTMP)protocol for that.So I have set up my Red5 server behind the Apache web server.The problem is that everything goes on well for 45-50 seconds and suddenly the RTMPT connection gets closed.I am not using a dedicated rtmpt server,i.e. I have not uncommented the rtmpt bean in the conf files.Rather I have added entries of servlet mappings(for idle,fcs,open etc) in the web.xml of my application. RTMPT is listening on 5080 port.I have tested this with previous versions of Red5 also but the problem is the same.The RTMPT connection closes after some time(within a minute).I had gone through logs but there was found nothing regarding this.Also there was no connection closure due to the inactivity period.Has it something to do with Apache? I am not sure whether server is closing the connection (though I cant find any logs about closing connection) or client closes it.Tried it out with 0.9.0 and 0.9.1 too but nothing to avail.I have heard that there were issues using RTMPT with Red5 on Mac but I am on Windows.Any pointers to this problem? Any help is appreciated.Also here are the error logs that I get on my Apache web server -
[error] (OS 10048)Only one usage of each socket address (protocol/network address/port) is normally permitted. : proxy: HTTP: attempt to connect to red5serverip:5080 (*) failed.
The same log is repeated for four times.
Here are some access logs from Apache too -
"POST /send/IDTK7NOG2PXGB/803 HTTP/1.1" 200 1
"POST /send/IDTK7NOG2PXGB/804 HTTP/1.1" 503 323
"POST /send/YXF4WTFMN8TCM/1391 HTTP/1.1" 200 8285
"POST /send/YXF4WTFMN8TCM/1392 HTTP/1.1" 200 1
"POST /send/YXF4WTFMN8TCM/1393 HTTP/1.1" 200 54

"POST /close/YXF4WTFMN8TCM/1396 HTTP/1.1" 503 323
Thanx!
Probably you are running out of tcp ports. A tcp connection will remain 4 minutes in the TIME_WAIT state by default, even if it is already closed. When your RTMPT stream uses 5 connections each second, your system will need at least 5*60*4=1200 ports for each connected user.
Often the firewall is limiting the amount of ports available. You can also decrease the keep-alive time of a tcp socket. If you google around with your apache error message you will find enough info to sort this out.
Your red5 server may be crashed. This occurs when your RAM usage is getting over. In that case you need to manually start red5 again. If this solved your problem, you need to upgrade your RAM. I am using about 8GB RAM after facing this problem several times. Because red5 was written using JAVA, it lacks memory. FFMPEG is good to use in a low memory. But I don't know how to provide chat using ffmpeg, exactly.
The 503 means that the service did not respond; if you are forwarding to red5 via apache, then this means there is a problem there. I would suggest not using the stand alone rtmpt bean; instead use only the servlet and remove apache from the mix to debug the issue.
Currently we have an Apache 2.2.3 server with mod_ssl 2.2.3 running Django, with users authenticating by using a x509 certificate.
So far the system is running perfectly except for a single user, who when trying to upload a file receives 400 Bad Request error, and the contents of the ssl_error_log regarding this operation are:
[<date>] [error] [client <client ip>] request failed: error reading the headers, referer: <referrer url>
The contents of the ssl_access_log are:
<client ip> - - [<date>] "POST <target page> HTTP/1.1" 400 321
Also, the user's browser is Firefox as far as I know.
I am completely unable to reproduce this bug and so far none of the other users have experienced it. Could you point out some reasons for this to happen?
I've experienced connectivity that stops the upstream after an X amount of bytes is sent. X was a pretty low value, as in enough to request some simple pages, but not to deal with ajax requests much less upload files. As far as I recall, this connectivity problem occurred only when tethering (from a specific Android phone, but I didnt even test other phones).
So if the upstream gets interrupted and the upload stalls, it makes sense apache would return this error, according to this post: "Apache waits a time equal to the Timeout directive (defaults to 5 minutes if not defined) for a response from the client. It is likely Apache is waiting for the CRLF that indicates the end of the headers, yet it is never received.."
I have a repository in here http://repos.joomlaguruteam.com/
I can browse it but I can clone it.
Every time I clone it I have this error
hg clone http://repos.joomlaguruteam.com/hello
destination directory: hello
requesting all changes
abort: HTTP Error 404: Not Found
and the access log have that

What is the problem.
I really hope somebody can help me with that.
Thanks,

I could clone this by using uncompressed transfer.
If you are using TortoiseHg, then check the box Use uncompressed transfer
If you are using command-line, then use --uncompressed flag
hg clone --uncompressed http://repos.joomlaguruteam.com/hello
