yes, but it was still holding on to those resources well after the unused
claim timeout.

the job actually attempts to start. The ownership of the resources is
given from DedicatedScheduler to the user, and the log file indicates that
the job started running. It fails to start, so the resources are given
back to DedicatedScheduler, which again gives them to the user and the job
again fails to start and so on.
