[Clueless guessing here...]  Are you able to correlate the error
messages with accesses to perhaps the same file from a different client?
If you suspect a race between two rename_file()s, one could well imagine
a first call to succeed, and a subsequent to fail when the source file
is already "renamed away".  ???

Hmm, from the CVS manual ('info cvs', node Error messages):

`cvs [checkout aborted]: cannot rename file FILE to CVS/,,FILE: Invalid
argument'
     This message has been reported as intermittently happening with
     CVS 1.9 on Solaris 2.5.  The cause is unknown; if you know more
     about what causes it, let us know as described in *Note BUGS::.

I wonder if this is related?  Although I think your errno is No such
file or directory (ENOENT), not Invalid argument (EINVAL).

BTW is your repository on a local disk or on an NFS mount?  (Not sure
it's relevant, maybe it helps someone more clueful.)

No problem; I was just trying to prevent any misunderstanding.  Bear in
mind you may have difficulty getting answers from a group of volunteers
(unless you have paid for support) to questions that indirectly solicit
"obligations".

Good luck.
