What version of Condor are you running on what O/S?

This isn't the cause of the problems, but concerns me.  If I'm reading the 
code correctly, this error means that the user/job log code couldn't lock the 
log file to log the error.  Do you have a low file lock set on your system or 
some such?  In general, you shouldn't see this, I think.

Now, this is where the actual error occurred.  Knowing which version of Condor 
could help narrow down where it went wrong.

I don't think that this should be an issue.
