I appreciate everybody's thoughts on this. I agree that the NFS looks to be the bottle neck however we have 5 other load balanced web servers that are pulling the web data from our NFS server. We mount the partition and then created sym links to those mounts. The other 5 web boxes are up and running fine. It is the sixth alone that is having this issue.
The first 5 are BSD this is a Fedora installation as we want to get away from BSD. Any other ideas? thanks, Adam ----- Ryan Simpkins <[EMAIL PROTECTED]> wrote: > On Wed, March 28, 2007 11:44, adam fisher wrote: > > apache 17268 0.7 0.6 29552 12868 ?
