Hi all,
Someone know if the kamailio 1.5.0 has problem to create and release tcp
connetctions after some time running? In my SIP network I have six IP
telephones and one gateway registered over TLS, after some time (one day)
this devices have problems to register and make calls. I noticed through
the log a freezing of kamailio when it try release the tcp connections.
Below is part of the log where I notice this behavior:
*Dec 28 09:46:46 vts74 /home2/local/kamailio/sbin/kamailio[8951]:

I know that upgrade to kamailio 3xx is recommended and I'm working to do
it, but before, I have to understand this behavior.
Cheers

TLS was really experimental
in 1.x, I don't think anyone here among
developers is going to sped time troubleshooting it.
General hints, attach with gdb to the pid and do a backtrace to see what
is doing. Check with netstat the state of the connection, too.
Cheers,

Hi,
kamailio 1.5.0 has slow to treat requests after some time running with
devices over TLS. About the state of the connection, I noticed that the
gateway doesn't has keepalive to tcp connection, so, after two minutes idle
this connection is released by timeout and other are create in future
requests. Maybe this behavior constant to create and to release tcp
connections can cause the problem because when I decreases the time of
Register to gateway (100 seconds) the connection is always kept and problem
doens't happen. I think that the child responsable to manage the tcp
connection is crashing and after some time all requests that use tcp
protocol, including acess to the database postgres, freezing.
If someone has other informations to help understand this behavior, will be
great!!!!
Best Regards
