Re: [Condor-users] Locking errors with dagman?

["Todd Tannenbaum" <tannenba@xxxxxxxxxxx>]

re the below -

If you know that each job will log to its own event log file (i.e. you do not have multiple jobs writing to the same log file), you can safely put the following into your condor_config file:
  ENABLE_USERLOG_LOCKING=FALSE
to solve the problem.

Happily, the next version of Condor due in Oct (v6.9.5) restructures the way user log locking works, and hopefully headaches like the below will become history in most environments.

Todd
