I see high CPU average load several times a day on my server. For example, 21:20 and 22:45 on the following figure:
However, my CPU, disk, and network are all OK:
- Disk
- Network
- CPU
- Memory
- Also do not see strange forks
- Interrupts also ok
I have read through many posts like this, this and this. But they mostly talk about some issues in network or disk, and my network & disk seems OK.
So what should I do? Or, is this even NOT a problem? Any suggestions will be appreciated!
