[SR-Users] Kamailio Crashing when using Evapi with CGRateS

[Efelin Novak]

Hi folks,

I am doing some experiments with Kamailio and Cgrates. To be precise I am
testing evapi module. When in testing environment I do not have any
problem. After redirecting some production traffic to this kamailio, It
crashes in at random times (few minutes to 20). I didn't find any pattern
here.

CGRateS doesn't write anything in logs.

I'm on the last 4.4 Kamailio (compiled recently). CGRateS is on the last
version.

Can you please point to how to continue with debugging?

Thanks

Efelin

Here is the problem in syslog:
