Hi.

Here is the output from vmstat 5 command on our web server:

[URL]http://pastie.org/629672[/URL]

Looks like system column (sy) is too high and I’m trying to figure out what could causing that…

Is there any tools I can look at to trace it?

I would really appreciate any suggestions!

Thanks

Hi there,

This could mean a lots of things.

At first I think you should try to run top -d1 to see which application of yours is eating up all your cpu.

Looks like it mostly httpd (Apache)…Is it possible for Apache to cause high system usage? I was thinking it should affect user column…
