[Bug 582596] [NEW] NFS bug renders machine nearly unusable due to oom-killer

[ichudov]

Public bug reported:

This machine is a NFS server. When I was using NFS heavily to copy music
files to my laptop, this server slowed down to a crawl. After a night, I
found it at load average of 80 with OOM killer rampaging.

The first error in /var/log/messages will be listed in the file I will
attach in the next message.
