<div dir="ltr">Hi Daniel,
<div>This happens randomly. It is not a testbed and never
reproducible on the test server. I can still give you access
if you wish to analyse the core files to check whats
happening here exactly.</div>
<div>It simply feels like on heavy load the evapi socket gives
up. Earlier I was running 5.0.2 and in that kamailio would
get stuck by not sending any async events on evapi socket.
Not even the evapi:connection-closed event gets triggered.
After I upgraded to latest stable version (5.1.5), it at
least started crashing. Here are two core dumps put onto
pastebin.</div>

<p>Is it on a testbed where I could get access to
investigate the corefiles? If not, then I will ask for
more details from cores over email, first would be 'bt

<p>Hello,</p>
<p>the backtrace doesn't show any hint about
kamailio, only from closelog() up.</p>
<p>It may be the core generated by shutdown
procedure, have you enabled one core file per
pid/process? If not, do it and reproduce the issue
again, you may get two core files, one being the
runtime issue and the other one from shutdown
procedure, which likely is an effect of the other
one. The one from the runtime is more relevant.</p>
