If you need any more information, just let me know. Gareth, the slow increase of load over months was there with 11.5 or 11.6 already, but I can live with a restart every couple month. Once every week is too much. Here is another overview of the load of one machine: http://pbrd.co/1zeFwBy You can see, the Asterisk was running from April to September without much change in load, then was restarted. In November, we updated to 11.14, and from that time, it looks a bit different (and Asterisk needed a lot more restarts).

Re: [asterisk-users] constantly increasing load in Asterisk 11.14 (Sebastian Damm)
Have you considered doing a daily reboot? In our shop (about 14 sites, busiest doing about 90 000 calls per day) we found it best to reboot each Asterisk instance at 23:45 - we're still running an ancient version (1.8.0.11). Once this regime was instituted our major Asterisk issues stopped, especially load-related issues linked to uptime. Note that we do not just restart the Asterisk process, we reboot the entire machine. We're running on bare-metal on Centos 6.5. Maybe you can try doing that, if at all practical? Our business needs fortunately this side is telecoms are only requires 08:00 - 17:00...

But since we upgraded to 11.14.0 a couple weeks ago, we have to restart the Asterisk process every week because the load gets too high and our monitoring complains. Those machines are doing only SIP-to-SIP call relay, the dialplan is quite complex, transcoding is done only on a few percent of the calls processed. During the daytime, there are at max around 200 SIP channels (100 calls) running at the same time. After one week, one machine has processed about 170k calls. I have uploaded a comparison of cacti load graphs for one week of a machine running with 11.14.0 and one running with 11.6.0: http://pbrd.co/1v0SO3R As you can see, after a restart, both machines have about the same load. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Can you tell me if the memory usage by Asterisk is also increasing with load over time?

We see it in the certified version which is currently 11.6. We have about 50% higher call volume on our servers than yourselves and it does take about 3-4 months for the load to reach about 5. I don't know what causes it but we take the servers out of our load balancing and restart asterisk every few months and this returns the load to normal. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
