Correct.

I have had this exact same problem once in which I believe 2 files in a 
squid cache were "damaged" which caused this exact behaviour.
This also means that the size of the file does not really matter since my 
files were just a few K large.

I did not have a kernel with kdb or had the brilliant idea of running mount 
through strace.

So untill someone encounters this behaviour and debugs it I have no clue 
whatsoever.

The squid cache was not heavily loaded or very large and was already 
working for more the 6 months. I guess something broke in mysterious ways. 
This box is also running XFS 1.0.2 it was also the /var partition but just 
1.5GB large. I have faith in the hardware since this box ran fine for over 
a year.

The mount problem is not really a problem with the 1.0.2 release perse 
since the Linuxcare Bootable Toolbox CD (see FAQ) has a different kernel 
althogether.

It was my first failure I have seen of a XFS filesystem that I did not 
cause myself.
