[OpenSIPS-Devel] OpenSIPS Crash

[Ben Newlin]

We have had 2 more crashes today.

Crash 2: https://pastebin.com/rMruBQcZ
This crash appears to have occurred while processing an initial INVITE request. I could not see anything unusual about the request. I cannot tell if this crash is related to the others.

Crash 3: https://pastebin.com/Gmk1m4NT
This crash follows the pattern of the original crash I reported.

Hello,

We have been having sporadic crashes and I was recently able to recover a core dump for one. I have uploaded it here: https://pastebin.com/ABktcYcH.

I picked out a Call-ID from the crash data and took a look in our tracing. I have uploaded it here: https://pastebin.com/ZEzUUKZ5.

It appears that a downstream server was extremely lagged and failed to respond to an INVITE. We sent the INVITE to another server and the call was connected, but then eventually the original server “caught up” and sent a burst of 200 OK responses. The crash seems to have occurred processing the ACK to one of these responses.
