So have you ran validate_repo (or check_cvs, if you're using 1.11) [As Larry 
suggested] lately?

There may be corruption lurking somewhere in your repo that you just have not 
noticed...  My memory may be failing me, but many of the times that I have 
seen NFS corruption, either personally or on this list, it was in the later 
parts of the file, i.e., after the current version... So you would not see the 
corruption unless you tried to check out an older version.

validate_repo|check_cvs may not be perfect, but they look for the usual 
suspects of problems.

After the first detection, I set our server up to run that script in a cron 
job so I could catch the faults before we rotated over the last good backup 
before the corruption.  Fortunately we moved to having the cvs server 
processes run on the file server, and I have not had to ware that tee shirt 
out for ~5 years now.
