Hi Friends,
We have a 100% CPU utilization problem and the broker hanged on our production system running on HP-UX.
Due to time crunch I had to restart the message broker without giving it a thought. But, what should be ideal first step if the message broker hangs ?
Regards,

Is it probably one of the ExecutionGroups executing code that is in a loop (or some other sillyness)
Find the pid of the EG and kill it. It will automatically restart.
Should not happen in a Production Environment

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

Find the most recent change to a flow in the broker.
Reverse this change.
Tell the developer his flow has a loop in it.

Hello All,
Is there any command or steps like refreshing of "Message Broker" who can done the job without need to kill any process ?
And, how we can isolate the problem to a particular message flow.
I know through process ID we can pin-point to a particular execution group, but is there any way to pin point to a particular message flow.
Regards,
Rahul |

Is there any way we can point the problem(memory Utilization) to a particular message flow. |
