Hi Greg

That's interesting and very worrying - surely it can't/shouldn't happen!

I have been using NFS for years for all types/sizes of files and
never had a problem until the last couple of months.

1.  The Centos/RHEL 5.3/5.4 kernel had a serious bug that has been fixed with the
	latest kernel update

2.  Now this F12 problem

Surely a very large worldwide community uses NFS ?

OK the F12 case could be my finger trouble or even a hardware problem

I will install F12 on a second machine and test again (against the same server)
