The original poster is running an HP cluster system with Tru64 v5.1!  
Linux has nothing to do with his issues.

Probably a good point, but again, he is limited to the filesystems 
available under Tru64. I have only used HP-UX up through V10.0, and am 
not familiar with Tru64, so cannot comment on that....

Probably the best solution - but maybe not what his customer will want 
to hear....

Wolfgang:  is this on a raid array, or some type of other storage 
array?  Could that be the bottleneck?  Is the NT system using 
comparable storage hardware?
