Possibly the job is requesting a complex whose value is determined by a load sensor and the returned value is not suitable but not causing an alarm. Alternatively perhaps a higher priority job with a resource reservation in place? We run with schedd_job_info false so I don't have much experience with it but I would expect qstat -j to take reservations into account while qalter -w [pv] can't as they're basically just doing the calculation for that one job. -- William Hay <w....@ucl.ac.uk>
