@miconda i don't think its related. the issue on
[adc4493](https://github.com/kamailio/kamailio/commit/adc4493fa6861895bdcf8b459e5fbc76e80d0f1f)
was to prevent crashing after leak that led to shm exhaustion.
in our case it was a instant shm exhaustion not a slow leak. the slow leak
could be related to the growth in xavp_rcd_helper or lookup_helper.
i still need to proof this but my theory is that different processes accessed
the contact xvap or the ulrcd in shm during xavp_clone and created a circular
reference. something like a register and a notify (that calls lookup) at the
same time. the server worked stable for 2 weeks, no shm growth, suddenly shm
was exhausted, and this unprotected xavp_clone made sip workers died and server
became unresponsive.
btw, is there a way to create/generate/force a core file with the contents of
the shm mem ? the core files we got (from sip workers) could not access the shm
mem to see if the shm xavp's contents could proof my theory
