[Mauiusers] Jobs stay deferred after adjusting ressource

probably a beginners question ;
I'm running torque 2.0.0p7 and maui 3.2.6p14 on a dual-node cluster.
Jobs that are submitted with overly large ressource requirements (e.g.
requesting more memory than available) go to a 'deferred' state and
'checkjob' reports something like :
job is deferred. Reason: NoResources (cannot create reservation for\
job 'XXX' (intital reservation attempt)
However, when I adjust the ressource request (using 'qalter') I would
expect the job to occasionally run (in particular after issuing a
'releasehold -a XXX' ). It doesn't and checkjob now says:
Messages: cannot create reservation for job '624' (intital reservation
PE: 17.57 StartPriority: 100
job cannot run in partition DEFAULT (idle procs do not meet requirements:
0 of 16 procs found)
This looks as if maui is still calculating the PEs with the old ressource
request (the job wanted 16 procs and ~10% more mem than available).
The job, when freshly submitted with the adjusted settings, runs fine.
So my question: Isn't maui informed about changed ressource requests ?
If no, how does one tell maui ??
I do assume that it's not a torque problem since qstat displays everything
Any help much appreciated,
