Has anyone experienced MQ locking up a W2000 box? This seems to occur when adding another QM while an existing QM is up and running. The other "live" QM's and channels remain active, you just can no longer access the mq explorer or anything else, a reboot is the only fix. This is a bit of a pain as now I can only add QM's and their channels during non-prod hours. I havent seen any documentation on why this issue would occur. Prehaps its just an undocumented feature.

What version of MQSeries and what CSD level?
You shouldn't need a reboot after simply creating a queue manager. Is there anything else on the box? Monitoring software for example?
Any FDC's being produced?
Any messages in the error log? |

| An *.FDC file is a file that WMQ will put in the errors subdirectory which will (for some problems) contain information that can be used to further diagnose what is wrong. |

No such animal. 5.3 is the latest version. Can you confirm what level you are at?

| There may be no event messages in the event log, but what about the error logs for MQ Series...anything there? |

This could be a symptom of having more than one listener on the same port for a different qmgr.
Check the ports your listeners are slotted for. Remember default is 1414
Enjoy  |

Starting at the beginning - what do you mean by locking up.
Does the system become unresponsive, ie is something at 100% CPU perhaps. Does the mouse move? Does the cpas lock yurn the light on the keyboard?
If its a total lock up (no mouse movement) then I'd look slighty further than MQ - MQ is an application and contains no non-ring 3 code, and hence the most it can (should be able to..) do is corrupt its own address space, not bring down the machine. Such hangs are nearly always caused by device drivers.
If 100% cpu, which process - Leave task manager running and visible, and ordered by cpu usage, with the top part visible (ie who is using the cpi). It will update slowly but should become obvious. |

I will try to answer all in one reply.
Version is 5.3 (fat finger earlier)
service pack is 7
all QM are on different listener ports
Lock-up.... still have mouse movement, cpu is low %( and that is what is confusing), task manager takes minutes to come up, unable to open ms explorer or console at all. when task manager does come up there is no application "not responding", no process has 100 %cpu and again the cpu % is very low (5-10 %)
weird, huh ?

| Is the hard disk being thrashed (perfmon i/o pages?)? How much memory is free in the machine at that point in time (ie is it possible the machine is continually paging)? |

| It sounds possibly network related. Something is probably trying to communicate in the background but timing out at the lower levels. When these timeouts occur, they can sometimes bring the whole system to a crawl, waiting for the timeout to expire. If a bunch of them are occurring in sequence, it will appear as if your system is locked up. Do you have a packet sniffer to catch what is going in/out of the system? That may give you a clue. |
