Hi.
My kamailio v4.4.5 installation ( -m 512 -M 64 ) stop sip processing with
fm_search_defrag(): fm_search_defrag(0x7f39917fa010, 952); Free fragment
not found!
core; Free fragment not foun
while it was enough free shared memory according to
kamcmd> core.shmmem m
{
total: 512
free: 472
used: 27
real_used: 39
max_used: 51m
fragments: 37035
}
whether it was about package memory or smth else? Thanks!

Hello,
for how long it was running? Was it any stress test or just normal traffic?
The issue is related to pkg memory, to get the stats of it per each
process, run:
kamcmd pkg.stats
Cheers,
Daniel

No any tests. It was running two weeks and crushed in out of peak period.
i have never seen this before in the months of uptime. Will start
monitoring pkg memory from this moment too.

If it is already running for some time, run:
kamcmd corex.pkg_summary idx 1
and then get the related qm/fm status/summary log messages from syslog
and send them here to check if there is any potential pkg leak in the
sip worker one.
Cheers,
Daniel
