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]:
DBG:core:io_watch_add: io_watch_add(0x816cc80, 25, 2, 0xb61e6558), fd_no=20

Dec 28 09:47:26 vts74 /home2/local/kamailio/sbin/kamailio[8951]:
DBG:core:io_watch_del: io_watch_del (0x816cc80, 30, -1, 0x0) fd_no=21 called
*

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
