[OpenSIPS-Devel] OpenSIPS Crash

Bogdan,

Sorry, I should have thought to actually look at the trace and examine this call.

1) Yes
2) The Called Party is 10.32.20.60, which is another OpenSIPS instance. The crashed instance received the "503 Service Unavailable" approximately 8-10 ms after sending the INVITE.

There is a SIP trace of the exchange here: https://pastebin.com/6bttsSVD.

One oddity I saw is that the crashed process appears to send (or at least siptrace) the ACK twice.

Hi Ben,

Thanks for "another" report :).

Questions:
1) do you do any async for the INVITE in this crash ?
2) if it is an YES to (1), is the caller party generating the "503 Service Unavailable" (which triggers the crash) - 10.32.20.60 ?? - a really close (from net delay perspective) and fast to answer party ?

Regards,
