Hello Experts,

We are seeing an issue where one job of the batch remains in idle state despite having resources available in the cluster. This started happening after the update to 8.8.5, we never saw this behavior with the 8.5.8 version.

Hi Vikrant:

Can we see (off list, if you so desire), the StartLog on the worker node for the claim failure in question?

-greg

We are using scheduler level splitting of slots.Â

# condor_config_val CLAIM_PARTITIONABLE_LEFTOVERS
true

Whenever this issue happened we noticed "Request was NOT accepted for claim" in schedlog which I believeÂindicates one failed attempt was made but then another attempt was made approx after 21m this time the job started running.Â

# grep '2290171.0' /var/log/condor/SchedLog
08/27/21 00:22:30 (pid:9386) job_transforms for 2290171.0: 1 considered, 1 applied (SetTestTeam)

What can we do to speed the job matchmakingÂafter the first failed attempt?Â

Thanks & Regards,

Vikrant Aggarwal
