Friends,

My Linux and Squid (100 ~ 125 requests per second) run unstable every
2-4 hours. Reloading Squid make the system back to normal (the problem
again within 2-4 hours), everytime problem happen.

I suspected that Ext journaling is the source of problem. I included
the Ext3 journaling as a kernel part instead a module.

Does the Ext3 journaling consume so much resources? Is it any
experience to
use Ext3 journaling?

Your advise is very appreciated.

Thx & Rgds,

Awie
