I have a strange issue happening on my Solaris virtual machine: After it is booted and up for 1-2 hours, the CPU usage will go up to 100% for 5 seconds, then down to normal for another 5 seconds, and repeats like that until a reboot - it makes my Solaris virtual machine totally unusable.
I wish to find out what is happening during the repeating 5 seconds 100% CPU usage, but the system is totally unresponsive during the 5 seconds - not even mouse/keyboard interrupts are handled, and thus I cannot see the process name using
So I wish to find out:
- the process id which caused the 100% CPU usage
- what the process was doing during the 100% CPU usage
Please offer your suggestions, thank you!
