Re: [reSIProcate-users] seg fault in Connection

[Byron Campen <docfaraday@xxxxxxxxx>]

There is at least one fix to some invalid memory management in the transport read buffer code since 1.5. It would have been committed sometime in April of 2011 I think (after the SIPit in Huntsville). I will try to give it a look later today. You probably want to update; lots of crash fixes in addition to new features and performance improvements.

Best regards,
Byron Campen

A lot of work and testing was done on TCP transports in general after 1.5 (ie. EPOLL support).  There's a good chance whatever is causing this was fixed.  I'm not sure what this could be offhand.

Hi!

I got a segfault today. Not sure what triggered it.

We still run resiprocate 1.5, but the code doesn't seem to have changed that much compared to 1.8.

I should add that we run ConnectionManager::gc() at regular intervals to kill of old TCP-connections, but from what I can see the dtor of Connection removes the connection from the manager.
