No, both fileservers are 1.6.0pre2.  But I thought it might be
significant that the 6GB file resides on a volume created by 1.4.x while
the target volume is created by 1.6.0pre2.

I do have an strace log of the fileserver when the client fails but have
no idea what to look for.  I didn't see any seek calls in it.  It is
about 120 megs of plaintext.  I can compress and post it somewhere if it
would help.
