[SR-Users] Weird out-of-memory message on start/stop

[Andreas Granig]

Hi,

Maybe some of you have encountered this funny error message when 
starting and even killing kamailio on a Debian 6 with 2.6.x and 3.x 
kernels and 2.11.3-4:

#-------------------------
# /usr/sbin/kamailio -f /etc/kamailio/proxy/kamailio.cfg -P 
/var/run/kamailio/kamailio.proxy.pid -m 4 -M 16 -u kamailio -g kamailio

# killall kamailio

#-------------------------

The PID reported here is the kamailio attendant process. It seems to be 
somehow related to the shared memory. The interesting part about that is 
that kamailio really starts just fine, and there is plenty (>5GB) of 
free memory available. It doesn't seem to influence the behaviour of 
kamailio at all as it's working perfectly fine, so for now it's just 
annoying, but I'm really curious

I've tried to fiddle with mem_join, but it doesn't matter whether it's 
on or off.

Kamailio version is this:

Has anyone seen this too? What's the cause of that?
