We have 2 sites on a VPS and we have been consistently experiencing high load and outages at specific intervals at the same times each day. The WHM is fairly standard, we have not installed anything other than what came out of the box.
Our WHM details:
WHM 11.32.3 (build 21)
CENTOS 6.2 x86_64 kvm on 500311
I have attached a snippet from our pingdom monitoring which shows that the outages are occurring at regular times each day. The times listed below are the approximate intervals
4:17 - 4:21
5:17 - 5:19
8:17 - 8:20
15:16 - 15:18
21:13 - 21:14
23:18 - 23:23
We have taken a look at the logs but are unsure where exactly to look and how to interpret them so any help would be greatly appreciated. We have asked our hosting provider if anything is happening on the KVM host at that time and they seem to think there is nothing that would cause that.
I have attached the sar log because that seemed to have differences that lined up with the intervals.
Thank you in advance for any help
