The SYSGEN parameter MAXJOBS is not referring to "Batch Jobs", so don't mess
with that for your problem.

Each batch queue has a setting called JOB_LIMIT which limits the number of
concurrent jobs that may be executing in that queue. Use the Command
 $INITIALIZE/QUE/JOB_LIMIT=n <queuename>
When the queue is in the STOPPED State.

If you have a log file for the executing job, wait one minute for the system
to flush the log output to the file and you can type the log file to see
where your job is hanging provided that VERIFY is on in the command
procedure.

If it is in an executable, what state is the process in? HIB? LEF? If LEF it
usually means that it is waiting for I/O to complete. If this is the case,
you can usually find out what it is waiting on using the system dump
analyzer.

If you need more details here, let me know.
