Auto reboot

Post by shafik.ete » 2016/09/21 10:25:42

Hello,

I am using centOS 5.9 version in my server and the server restarts automatically after every 48-60 hours. Following message logs are found from /var/log/messages just before the restart happens:

kernel: BUG: scheduling while atomic: swapper/0x10000200/0

CPU utilization found upto 30-40% at the moment of restart. Can anyone help me to find the reason of this auto-restart problem.
Thanks.

Update to the latest version. 5.9 has been out of date since the release of 5.10 in October 2013 and the current latest is 5.11 which was released in Spet 2014 and has had numerous critical security updates released since. Run yum update to get to 5.11 + latest. Your current version came out in Jan 2013 and is now 3.5 years out of date.
The future appears to be RHEL or Debian. I think I'm going Debian.

Dear TrevorH,
Thanks for your reply and suggestion. But, I am using the same version OS in my another SIP server where everything is fine. In both server, I am using VOS application. 1 with UDP open and another with UDP closed. The server of closed UDP is the problematic one. What could be the reason behind. any idea?

It doesn't matter if you have one that works, you still need to udpate! You are missing 3 years of security fixes and could be exploited at any time.
