My commands to start a queue simply hangs

I checked the AMQ log for errors, but there are no messages written to thiese logs today (the last message was yesterday)

I checked as follows:

Code:
ps -ef | grep mqm
root      6610  6585  0 10:11 pts/1    00:00:00 su - mqm
mqm       6611  6610  0 10:11 pts/1    00:00:00 -bash
mqm       6720  6611  0 10:20 pts/1    00:00:00 strmqm BBB
root      6765  6727  0 10:23 pts/0    00:00:00 grep mqm


What should I do next to determine the problem ?

Check the syslog.

Why do you need to start the queue manager? Is it new, or an existing queue manager? If the latter did it close normally?

Try this control command: dspmq ; then post the results here.

strmqm tries to start other processes like amqzxma0. It has evidently failed to do that, which is very strange. My guess would be a locked file (are your files on NFS? what version of NFS?) or problem with semaphores. Did you check in /var/mqm/errors for any .FDC files?

IBM have a suggested way to dump state for "hang" symptoms if you were to need to open a a PMR .. go to this page http://www.ibm.com/support/docview.wss?uid=swg21293105 which I found via the main "MustGather: Read first for WebSphere MQ" page
