Subject: Re: [SR-Users] Memory configuration

What is the value of shared memory you set for kamailio (-m parameter)? Maybe it is not sufficient for what you need to do.

Then what version of kamailio do you run (kamailio -v)?

The process that crashed (29438) has a different pid than the one (29468) printing the memory errors, so may or may not be related.

I feel fairly confident I’m running into a memory tuning issue, but I’m struggling to determine the next step. Can someone give me some guidance on how to adjust settings to allow the system to stop crashing kamailio?
