Re: [Condor-users] Jobs lingering in queue if target shuts down mid-job

I'm running 7.6.4 Todd, but thanks for the reply.

Is TCP_KEEPALIVE a condor configuration value? and is it safe to lower it (to 30 mins) or will it have any adverse affects?

- in the event of a execute machine crashing, the job should
automatically requeue after a maximum of 2 hrs (the TCP KEEPALIVE
timeout). we plan to enhance this from 2 hrs max to instead be the job
lease duration (default of 20 minutes) in a future developer series release.

- are you running the developer series of Condor? there was a bug
introduced in Condor v7.7.2 that could result in the job staying running
indefinitely depending on your configuration. we have it fixed for the
upcoming v7.7.4 release. details at
