I'm running wsmq V6.0.2 on Windows 2003 SP2. The box has 8191 MB RAM. I'm sending through a high volume of SSL transactions. There is nothing else running on the box.
Right after I boot the machine and begin processing transactions, 1.2 GB memory are in use in the page file. After 1 day, 7.6 GB are in use in the page file. I'm wondering if there's a memory leak here. Does anyone know about any known issues that could be causing this?
My app is written in VB.NET. The only objects that I Dim in the code that come from the IBM dlls are the MQQueue queues, message object, MQGetMessageOptions, and MQQueueManager. The queues I close in a finally block, I also disconnect from the MQQueueManager in the finally block.
So as far as I know, I'm getting rid of all the objects properly, which makes it puzzling that the commit charge gets up to 8 gigs in a day, and the physical memory in use is 7.6 GB. When I look at the running processes in task manager, I can account for around 1 GB, then there are another 7 GB that are committed that I can't account for, which makes me wonder about a memory leak.
Hope this isn't too much info, just wanted to be thorough in the description.
Any insight is appreciated.
Thanks! |

Which version of .NET are you using? You're not the first person to find a memory leak in this interface.
The search button will be your friend here.

| I've tried this in vb.net 2003 and 2005. Would one be better than the other? |

| Also, I've been searching around and seen some talk of memory leaks, but nothing that appears to address this particular issue. I'll keep looking. Do you know of any particular post? |

IIRC the .NET client isn't certified past .NET 1.0 and you've seen the issues for yourself. I don't remember anyone posting a solution.
