Hi all:
I have encountered a strange situation which my host went out of countrol
out of peak time.
top -S shows that CPU Sys. is over 90 %, and pagedaemon has very high
loading, then the server died.
Would anyone give me some advices to solve this queer problem?
Thanks and have a nice day,
Weicheng Pan.
