Can anyone help diagnose why RabbitMQ is failing to start? It has worked fine in the past, but suddenly is refusing to start. I'm running the command sudo rabbitmqctl start, and I get the following output:
Error: {'EXIT',
{function_clause,
[{rabbit_control,action,
[start,rabbit#BELLOMACPRO,[],
[{"-p","/"},{"-n","rabbit#BELLOMACPRO"},{"-q",false}],
#Fun<rabbit_control.1.100323439>],
[{file,"src/rabbit_control.erl"},{line,168}]},
{rabbit_control,start,0,
[{file,"src/rabbit_control.erl"},{line,84}]},
{init,start_it,1,[]},
{init,start_em,1,[]}]}}
I'm not finding this particularly informative, but perhaps there's something obvious to someone who better understands Erlang. The log file has no recent entries to shed any light on the issue.
I never figured out what the cause of the problem was, but I worked around it by executing the server directly with sudo rabbitmq-server, rather than attempting to use rabbitmqctl. Explanations are still welcome.

This is my first time asking a question here so I will try to be descriptive. I am relatively new to python and tensorflow, and have been learning it specifically for a project.
I am currently working to deploy a tensorflow model using tensorflow serving and flask with wsgi. I have been following this architecture: https://github.com/Vetal1977/tf_serving_flask_app
I am running tensorflow_model_server on port=9000.
I know that tensorflow_model_server is working, because when I execute the tensorflow_serving_client.py from command line, I get the expected response. I have tested this command line execution on every user account.
Similarly, I know that Flask + WSGI is working, because I can see log.info points dropping into the apache error log as it works its way through the script. If I return something before it gets to the line in question, it works just fine.
However, when the application is executed with Flask + WSGI, it hangs at this line: result = stub.Predict.future(request, 5.0) # 5 seconds (https://github.com/Vetal1977/tf_serving_flask_app/blob/master/api/gan/logic/tf_serving_client.py#L70)
I can see that it hangs as I monitor top and tail -f error.log and see the same apache process sit there until it is killed or apache is restarted.
I am really stuck on the fact that it works when executed via command line, but not when Flask + WSGI runs it. Can anyone provide suggestions or point me in the right direction? Am I headed down the right path with this? Any assistance at all would be greatly appreciated.
EDIT: I have uploaded the minimal code to a github repo here: https://github.com/raymondtri/client-test along with a minimal setup that does require flask, wsgi, tensorflow, and tensorflow-serving.
Thanks in advance,
Ray
After much research and many hours, I think that this has something to do with how mod_wsgi forks processes, and how grpc has some known issues with that. I have a feeling that things are getting orphaned as the process is forked and that is what is causing the script to hang.
I could be wrong though, that is just my current hypothesis.
BUT, doesn't fail when running the same recipe in debug mode.
Chef 12.11.18
After troubleshooting this issue quite some time now, I think the root cause of the problem is my ssh configuration.
Any idea how to fix it?
Thanks,

There was a problem with my ISV.
its been more than 2 weeks. i try to instal but still getting error.
firstly, indeed I have searched similar error but i didn't find solution at all. if you find it. please let me know.
second, this is my state :
1. i have installed python 2.7 and django 1.5.1 (it works).
2. i also install MAMP.
3. i try to configure mod_wsgi and want it integrated with my MAMP apache server.
4. using mac mountain lion 10.8.4
my configuration file :
/etc/apache2/original/extra/httpd-userdir.conf inside my apache2/original/extra/
/etc/apache2/users/akhyar.conf pastebin.com/zcY58WTV (sorry about this Iam new on stack overflow)
/etc/apache2/httpd.conf pastebin.com/je2D8zMz
third, this is my error :
when i run apachectl configtest this error appears my error
so, what is going on actually? can someone tell me why and show me the mistakes?
if its been solved, what is the next step for configuring mod_wsgi on my MAMP?
thanks before, any help are highly appreciated.
In this file, line 15, you're including the per-user conf files:
http://pastebin.com/7y7ibuqP
On line 473 of this one, one of those per-user conf files, you're including the above file again:
http://pastebin.com/zcY58WTV
This causes infinite recursion while trying to parse the conf files.
I think there are some other errors too, and to be honest the files are pretty messy, but the best way forward is to remove all Include directives from akhyar.conf. For the most part they're already duplicates, where they're not, inline the contents of those files instead of using Include. If there are other errors, you'll at least see useful line numbers to start tracking them down.
Also note that the [warn] lines are just warnings - which you should probably fix, but the server will still run without them, that's not what's causing the error.
I am trying to make an embedded Linux for a SuperH processor board. I am using the Buildroot 2012.2 toolchain with uClibc.
All compiles fine but when I try to run some of the BusyBox applets (for instance 'ls' or 'mount'), I get an error like this:
ls: : Unknown error 2
For 'ls' in particular it writes this error number-of-files-in-folder times.
Do you have any ideas what might be causing this? No one on the internet seems to have the same problem and I am crawling the configs for several days without luck.
I believe the error might be caused by misconfigured uClibc but it is just my guess.
Thanks.
EDIT:
I enabled several error message options in uClibc and now I get "no such file or directory" error.
I will answer my own question.
The first and most important problem was, that I have over-optimized uClibc so all reasonable error reports were not included. If you are reading this and have same problem, switch error messages on. They are quite small and very useful.
After resolving human readable error reports, I realized, that the putchar function was disabled. Enabling it solved the problem.
To future generation I advise extreme caution, which features of uClibc you decide to disable, unless you want to spend several days finding an unexpected bug.
When I try to run paster shell example.ini, I run into:
connection failure: TLEngine(postgres://reddit/password#127.0.0.1/reddit)
followed by a laundry list of traceback.
At the end, I get:
FATAL: password authentication failed for user "reddit"
Would anyone be able to help me resolve this issue? Any help is much appreciated. Thanks!
The Reddit Setup Guide seems to be out of date or something. I had the exact same problem as you on two different machines.
Here's how I overcame it:
$ sudo su - postgresq
$ psql reddit
reddit=# CREATE USER reddit WITH PASSWORD 'password';
I looked in the example.ini file and reddit/password was the default username/password for the DB. At this point, if you re-run your command (paster shell example.ini), it should complete successfully.
Fair warning, there are more problems with this setup after you get past this point, but I haven't yet conquered those myself.
Best of luck, friend!
