Can you reproduce the problem?

If we can reproduce the problem, consider the conditions under which it is reproduced:

• Is it caused by a command or an equivalent administration request?

  Does the operation work if it is entered by another method? If the command works if it is entered on the command line, but not otherwise, check that the command server has not stopped, and that the queue definition of the SYSTEM.ADMIN.COMMAND.QUEUE has not been changed.

• Is it caused by a program? Does it fail on all IBM MQ systems and all queue managers, or only on some?
• Can you identify any application that always seems to be running in the system when the problem occurs? If so, examine the application to see if it is in error.
