[OpenSIPS-Users] OpenSIPS crashed after "out of pkg memory"

Thu Jun 26 17:09:02 CEST 2014

Hi Bogdan,

We already have compiled opensips as described, and set memlog=1 in the
configuration file.
But as we had a lot of debug messages about memory usage, we unset memlog=1
in the config, so we don't have any report now.
Is there a way to get those messages in a different log file, instead of
inside the "classical" opensips.log ? I've found an option like "memdump"
that can be set in opensips.cfg, but what about it ?

And as cacti doesn't seems to be relevant to check opensips's mem usage, do
you have any other solution to check it ?

Thanks for your help,
