Re: [Condor-users] slight bug in dynamic slots

Hi Erik,

You can change tihs behaviour by setting variable CLAIM_WORKLIFE.
http://www.cs.wisc.edu/condor/manual/v7.4/3_3Configuration.html#16308

This variable specifies the number of seconds after which a claim will stop
accepting additional jobs.

Regards,
Lukas
