Re: [SR-Users] Memory configuration

This particular system is a test system, so there’s not a TON of activity. Though the system itself has maybe 8 GB of RAM. So we’re talking a handful of calls throughout a given day. The service appears to crash maybe once every couple of days. I bumped the SHM_MEMORY up to 512 over the weekend and restarted to see what impact that has. Which specific command are you looking for the output of, I’m blanking on which to run. *From:* Daniel-Constantin Mierla [mailto:miconda@gmail.com] *Sent:* Monday, September 18, 2017 3:17 AM *To:* Joe Baran &lt;jbaran(a)whitelabelcomm.com&gt;om>; Kamailio (SER) - Users Mailing List &lt;sr-users(a)lists.kamailio.org&gt; *Subject:* Re: [SR-Users] Memory configuration If you have a lot of traffic and registered devices, you can run out of it quickly. What is the number of registered devices and call setups per second/active calls at peak? When you do a restart, can you grab the stats and see what are the values for shared memory?

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.

Can someone give me some guidance on how to adjust settings to allow the system to stop crashing kamailio?
