NFS problems

[Trevor Jennings <trevj portland com>]

Hello,   

 I'm having a slight problem with NFS that a file that is being written to
on a NFS mounted drive keeps being reset to 0 bytes. I am using linuxPPC
R5 as the client, redhat 5.2 as the NFS server,  and  I basically setup
apache to save logs onto a nfs drive. The access log works fine, then
about 20-30 seconds later, the filesize is reset to 0 bytes. The error_log
file works fine although everynow and then resets itself. Is this a
problem concerning apache or NFS itself?

Cheers,
