Hi All,
I have recently build new servers with MQ 7.5.0.1 on Windows Server 2008 and see that there are too many amqzla00 process spawning and they reach a limit which makes MQ Queue Manager crashes, as I tried to google it found it's bad app leaving connection opened, but the strange bit is the same app on old servers with MQ 7.0.1.6 never reported this issue and it's surprising just beeter servers and MQ latest is the difference, I tend to not agree that app is same way configured as we do a complete fresh install of MQ same is for apps also could be they have missed something on new servers, but just in case is there something from MQ end I could do to keep a check on these processes, any suggestions please.
Thanks |

Also as I see in the Task Manager there a loads of process continouslly spawning as below with something called as a fip number
C:\Progrma Files\IBM\Websphere MQ\bin\amqzlaa0.exe -mQMGR -fip41
this fip number keeps growing and gets to 1000 also is the culprit basically |

Hi bruce2359 - yes I did, but there is hardly anything relevant out there with respect to 7.5 or moreover the issue I am seeing all I could find is below which is not relevant here as mine is MQ 7.5.0.1 and the FFST stack is different also
http://www-01.ibm.com/support/docview.wss?uid=swg1IC81798
Error description
FFSTs with probe id XY551007 for components xlsSpinLockRequest
and xcsFreeQuickCell are seen for the WebSphere MQ V7.1 channel
pooling process ( amqrmppa.exe ). The major errorcode reported
is xecL_W_LONG_LOCK_WAIT with probe description "AMQ6150:
WebSphere MQ semaphore is busy."
The FFST stack reports:
MQM Function Stack
rppDisconnectPool
xcsTerminate
xcsDisconnectSharedSubpool
xlsThreadTermination
xcsFreeQuickCell
xlsSpinLockRequest
xcsFFST
Local fix
Problem summary
PROBLEM SUMMARY:
****************************************************************
USERS AFFECTED:
WebSphere MQ v7.1 on Windows platform.
Platforms affected:
Windows
****************************************************************
PROBLEM SUMMARY:
The locking contention for the quickcell resources results in
this FDC.
Problem conclusion
The code is modified so that the quickcell resource usage is
optimized and hence the locking contention is reduced. This
problem is fixed through the internal defect 155891.1.
---------------------------------------------------------------
The fix is targeted for delivery in the following PTFs:
v7.1
Platform Fix Pack 7.1.0.2
-------- --------------------
Windows U200351 |
