Hi,
I'm running WMQI 2.1 GA on Solaris. Lately, I've been experiencing "Out Of Memory" condition with the broker.
We are a 24x7 shop and cannot afford to reboot the server every week. Our broker has 3 main ExecGroups, total 15 message flows. All flows are single-threaded. Most flows have to access DB2 for inserts. We're using the PostIt, GetEnv, LDAP PlugIn and MQGet supportpacs.
Any comments will be very appreciated.
Thanks |

How long have you been running without experiencing this condition?
If this was a reasonable period (couple of months?), what has changed?
Message troughput, Database upgrade, underlying OS patches, downtime intervals. The cause could be anything nothing to do with MQSI itself...

Actually, I have wmqi-upd04 (CSD02) on this system.
The latest CSD06 has a fix for IC35511 (Broker memory leak), CSD05 also has a fix for PQ66950 (Memory leak when using NEON). I can't find the description of those 2 problems anywhere.
Thanks |

Thanks.
I'm not using SCADA so I guess IC35511 does not apply to my shop.
NEON is used extensively but PQ66950 mentions on Z/OS. Does it also apply to Solaris ? |

I don't have personal experience with the Postit SP, but about a year ago I heard from another consultant that it leaked like a sieve (it might have been cleaned up since then). Based on that, we used MQGet for our requirements and haven't had any issues.
Good Luck.  |

I opened a ticket with IBM and was told that GetEnv may be the culprit.
Anybody experiencing memory problem with this SupportPacs ?
Thanks
