File system cache corruptions?

[James Pearson <james-p@moving-picture.com>]

Very occasionally we get problems where by an application on an NFS 
server fails to load on one NFS client - for example just had one which 
fails when you try to run it:

/path/to/nfs/mounted/binary: relocation error: 
/path/to/nfs/mounted/shared/object.so: symbol , version GLIBC_2.0 not 
defined in file libpthread.so.0 with link time reference

I 'fixed' the problem by running a simple tool on the client that just 
grabs memory - and hence flushes any cached files.

The application in question hasn't changed in months.

In this case, the client is running Fedora Core 1 with a 2.4.22 based 
kernel (with Trond's NFS client patches), but we've seen similar 
problems with Redhat 7.2 based machines with a variety of kernel.org 
2.4.X based kernels.

Any ideas on what may be causing this?
