[Freeswitch-users] Freeswitch 1.4.15 and a sudden jump in CPU usage

[Muhammad Naseer Bhatti]

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.
