Hi, We'd recently moved to 2.6.5 and I've definitely been able to submit to a reservation before, and it went off almost straight away. The reservation was specific to two accounts, no users were specified on it. I definitely did this several times yesterday. This was on the Blue Gene/Q, but I tried it just now on an x86 cluster and it also went off straight away.
Perhaps some extra debugging might reveal why the 2.6.5 was holding the jobs back?

I reverted to slurm 2.6.4 and an already submitted job that was not running with 2.6.5 started with no issues and no manual intervention after I restarted the slurmctld.
