Have I got a corrupt repository?

[Andy Jones]

[Red Hat 7.1, CVS 1.11.10]

I've been trying to check in a *big* change over pserver and getting some 
nasty crashes from CVS (which unfortunately I did not take a note of - 
"System exit 11"?).  Eventually I discovered that this particular client 
machine had an older version of CVS on it - 1.10.8 - and put it down to that.

So I FTP'd the big change across to the server machine and tried again, but 
I'm seeing some Weird Stuff:

* I have some files which cvs status shows as "locally modified" but cvs -n 
commit does not list.  If I do cvs commit without the -n, though, that's okay.

* CVS keeps telling me that it's waiting for a lock to be freed.  No-one 
else is using CVS, though.  As per the manual, I'm deleting the lock 
files.  But I've never had this problem before.

Do I have a corrupt repository?

If so, can it be repaired?  I can restore a backup of the repository if 
necessary, but if there's an easier way...
