Hello,

can you enable pkg summary and generate it once the out of memory happens?

Set memlog to lower value than debug, when the memory happens, do:

https://www.kamailio.org/docs/modules/devel/modules/corex.html#corex.rpc.pkg_summary

Then send some traffic to that process and watch the syslog.

Alternative, enable memory summary via core parameter and stop kamailio
when the errors happen, but you will get summary for all processes, so
it might be harder to extract those log messages related the evapi process.

Cheers,
Daniel
