that's odd. How many processors? can you tell me if it happens with
other file systems? If this is a read-only workload, you can prefix
the file name with 'ufs:' and take a different code path inside the
library.

p.s. i know this won't be very helpful to you but parallel I/O to an
NFS volume, while supported, is not going to perform very well, and
will likely, despite the library's best efforts, give you incorrect
results.
