Hi Andrei!
As promised, I recompiled kamailio with your patch applied.
First quick tests shows that error has gone. Server now able to initiate
TCP session and communicate with remote.
Will see how it'll behave under load ( after 14:00 CET ).
I will inform you if we'll face with stability problems.
Anyway, thank you very much for quick fix on this problem!

Hi List!
I'm running Kamailio for about 1 year without any serious problems.
When it works with UDP only, it runs perfectly well for us. Without any
major issues.
But now we have a customer who wants to connect Lync to our network.
Unfortunately, Lync does not support UDP for SIP signalling, so we tried
to teach kamailio to send SIP messages via TCP.
And getting strange error:
[...]

Could
you try the attached patch and report back if it works?
(I couldn't reproduce it on my ancient FreeBSD 7.1)
I think the problem is that newer FreeBSD versions return ENOTCONN when
attempting to send on a not yet fully connected socket (instead of
EAGAIN).
