Re: [Condor-users] Standard Universe Jobs - File Permission Errors

[jhowes@xxxxxxxxxxxxxxxx]

If you have not already done this, you should check what file causes 
the error.  Read or write?

Have you checked UIDs numbers for the userids on each machine?  Is it 
possible they are not in sync?  Group Ids also?

Just a couple things I would check for.
