Scott,

thanks for your help!

maui/gold charges in hours due to
ChargeRate Modify Type==Resource Name==Processors Rate=0.00027777

The checkjob -v had
job is deferred.  Reason:  BankFailure  (cannot debit job account)
Holds:    Defer  (hold reason:  BankFailure)

We do not use any prolog/epilog with maui, just with torque.

What I found out though maui added 10 minutes to the end time of the job due to:
RESOURCELIMITPOLICY MEM:ALWAYS,EXTENDEDVIOLATION:NOTIFY,CANCEL:00:05:00
RESOURCELIMITPOLICY WALLTIME:ALWAYS:NOTIFY,CANCEL:00:05:00

which may have gotten the debit for the requested time greater that the credit
(maui seems to round up to the next hour while moab only did so for more than 30
minutes)

I solved the problem with removing the reservations in gold
goldsh Reservation Delete Id==953163

and added some more credits and the job started.


Thanks again for your help.
Eva
