Condor can't rely on the file locking mechanisms of NFS.  In particular, user 
logs can get corrupted if written to by multiple writes (i.e. if you have 
several jobs running at the same time writing to the same log).  If your user 
job gets corrupted, this can confuse tools like DAGMan that rely on the user 
log.  We have seen this problem occur often enough that we felt it warrented 
the warning message.

Hope this helps
