I am facing same issue. Freeswitch taking more than 100% cpu usage in htop even on 200 concurrent calls. For 1000 concurrent calls i have to install 3 freeswitch instances due to this much cpu usage taking by a single freeswitch node. My Dist is Debian 7.

It looks like this is the same tickless kernel issue. I am using Debian 7 and the CPU usage shows very high. Adding nohz=off to grub options does makes it lower. I am gathering more information in order to file a Jira. Debian 6 on the other hand works very quietly on the same workload. We are talking about 200+% CPU utilization on Debian 7 and around 50% on Debian 6 showing in htop. I know so many other factors also involved but I am still digging out more.

same issue.
I have several FS 1.4.15 running on CentOS 6.5 x86_64, the CPU will be very high about 9:00 am every morning. there is no crontab at this time.
i will downgrade to 1.4.14 to see if there is such issue.

Hi Anthony,
I do not know if I am hitting a bug and if this is a bug, I don't have much info. I'm using this mailing list to see if anyone else is experiencing this problem and if there is a configuration change on Linux or Freeswitch that can fix this problem. Jira would be to report bugs when you know there is a bug. My problem could be (very likely) an environment related issue.
Thanks.

Also you will have better luck using JIRA. The mailing list is expressly NOT for reporting issues.

you might want to use gcore to look at the threads and see what is different when it in this state and not.
