Log warning on jitsi meet linux ubuntu - webrtc

In the jvb.log I have this warning on more rows:
"Got sctp association state update: 1
sctp is now up. was ready? false"
It's normal? Why?
Have you a solution for clean this message?
Thanks

Anyone have idea on what is the error?
Appreciate with your help. Thanks.
You must provide the RabbitMQ and Erlang version any time you ask a question or report an issue with RabbitMQ. In fact, any time you are talking about software, providing versions is necessary!
This is the important part of the error text:
{eacces,[{erlang,open_port,[{spawn,[67,58,92,87,105,110,100,111,119,115,92,115,121,115,116,101,109,51,50,92,99,109,100,46,101,120,101,32,47,99,32,100,105,114,32,47,45,67,32,47,87,32,34,92,92,63,92,"c:","\","Users","\","appadmin","\","AppData","\","Roaming","\","RabbitMQ","\","db","\","rabbit#FR-PPA004-mnesia",34]},
eacces means that there is a permission issue. Since I don't know what version of RabbitMQ you are using, my guess is that the free disk space check errors because RabbitMQ/Erlang can't start up Powershell or cmd.exe.
I have fixed issues around free disk space monitoring as well as to make RabbitMQ more UTF-8 friendly (in case you are using a non-English) language.
My suggestion is to upgrade to the latest RabbitMQ (3.11.4) and Erlang (25.1.2). If that does not resolve your issue, you should start a new discussion here.
NOTE: the RabbitMQ team monitors the rabbitmq-users mailing list and only sometimes answers questions on StackOverflow.

Aerospike Error while receiving on FD: 11 (Resource temporarily unavailable)

We are using Aerospike in cluster mode and when we enable the log severity to Debug, we are seeing error logged under debug level Error while receiving on FD 43: 11 (Resource temporarily unavailable). This is not logged as a Error severity in Aerospike though. so i am wondering is this an error we really should worry about or is this just some error Aerospike is encountering and it is handled automatically (that we can ignore in this case). we are continuously seeing this in the logs and worrying some lagging is happening.
thanks in advance.
I wouldn't necessarily worry if this is only logged at Debug level and there is no noticeable impact, but I am not certain... could be simply how epol works under aggressive workloads.
Cross posted on https://discuss.aerospike.com/t/getting-fd-resource-temporaryly-unavailable-in-cluster-mode/7030
This is an "EAGAIN" error (see http://man7.org/linux/man-pages/man3/errno.3.html):
EAGAIN Resource temporarily unavailable (may be the same
value as EWOULDBLOCK) (POSIX.1-2001).
Means the Aerospike attempted a non-blocking operation and the socket couldn't take at this time. The server will attempt the operation again later.
This isn't anything to be concerned of, EAGAIN and EWOULDBLOCK errors are expected.

What does this error error:140000DB:SSL routines:SSL routines:short read means

In our software, we are keep getting this warning/error message intermittently. Not sure how/why this message appears.
HTTP asio handshake failed: error:140000DB:SSL routines:SSL
routines:short read
I searched in the Internet, but the mostly the result pointing me to a VMware problem. Which not the case for me.
Until I found out that actually this error is thrown by OpenSSL that is used by Boost-Asio. I have downloaded the source code of OpenSSL/Asio/Boost but couldn't find this error code in the source. My question, Is there anyone knows what this error means? What could be the trigger of this error message? I just want to understand a bit to find out the reproduction. So we can fix our software if there is any hole in the software.
Many Thanks in advance!

how to clean boost::asio::ssl::stream after closed by server
A commit in OpenSSL removed the error SSL_R_SHORT_READ.
The commit before before OpenSSL removed the error SSL_R_SHORT_READ still has it defined as 219 == 0xDB. This error of 0xDB is what comes out of OpenSSL as 0x140000DB.
In general a short read happens on TCP when the connection ended before the other side could send enough data to decode the current message. This may happen for example because the other side crashed or a network problem.
Found the root cause for my problem. There is mismatch of cipher the host and the client that trying to connect to. Then this error is thrown from the client.

Server received ssl alert 0 "close notify" as fatal error

We have seen much more SSL error than before when we move to a new server. The total SSL error rate is not high. Many of them are:
error:140943E8:SSL routines:SSL3_READ_BYTES:reason(1000):s3_pkt.c:1256:SSL alert number 0
We finally found these requests are actually successful requests. Why these error was generated is that openssl found these were fatal error. Add more debug info show that:
ssl_callback_info:SSL_CB_READ_ALERT fatal error close notify
But from rfc2246:
7.2.1. Closure alerts
The client and the server must share knowledge that the connection is
ending in order to avoid a truncation attack. Either party may
initiate the exchange of closing messages.
close_notify
This message notifies the recipient that the sender will not send
any more messages on this connection. The session becomes
unresumable if any connection is terminated without proper
close_notify messages with level equal to warning.
We are wondering if there some special clients send "alert 0" as fatal . Or this related some known issue of openssl. We are using openssl-1.0.1e now. Before migration we used openssl-1.0.0-25.
Any suggestions would be appreciated.
Update:
I investigated the access log and found almost all the "fatal alert 0" was sent by Safari on Apple devices(Mac, iPhone, iPad).
Through the code of libsecurity_ssl which the library of SSL engine. I found that this library would send "fatal alert 0" in sometimes that was totally different with other SSL libraries, for example openssl, NSS.
SSLFatalSessionAlert(SSL_AlertCloseNotify, ctx);
http://www.opensource.apple.com/source/libsecurity_ssl/libsecurity_ssl-32463/lib/sslRecord.c
This mostly occurred when Safari meet unexpected abort of the connection. As my server would not sent a "warning alert 0" to close the connection.

What is JVM Bind?

I tried to run example from HornetQ and I got this error:
[java] HornetQServer_0 out: Deployment "JNDIServer" is in error due to: java.rmi.server.ExportException: Port already in use: 1098
Actually this is not the first time I got this kind of error. I can verify that port 1098 is indeed already in use (using Netstat command) but I just don't know which service using it. Is anybody has encountered such problem?
Thanks in advance for any response and help. :)
Could be JBOSS or Remote Admin Tool. Or something else like Outlook or Firefox.
