Does anyone know what type of object BLK_MQPOOL is?

 

I'm repeatedly calling a Java agent from LotusScript and I'm trying to resolve the cause of a memory leak in the Java agent.  I've performed a number of NSD calls and see that an object of type BLK_MQPOOL is growing in both the number of these objects and the memory they consume.  It's the number one object in the top 10 memory usage blocks.

 

Examples from NSD:

Checking VPOOL 0x8427 (BLK_MQPOOL) msize=16384, membrs=188/1024 Cap 15%

0x8427    3088290        188  BLK_MQPOOL

 

Am hoping if I can relate this type of object back to a part of the code I may be able to resolve the leak.

 

Thanks.

 

Alex

Some ideas, too.

If you've called recycle() obsessively & this turns out to be heap memory ...

I've noticed the garbage-collector doesn't get triggered often enough when there are Java agents / packages being called by LotusScript.

I rewrote the Java agents to 1) handle multiple docs in one agent launch, then 2) call garbage-collection explicitly after every 100-150 docs.

With the packages this was tougher. So I just added an agent to wake up every so often and garbage-collect.

Garbage Collection

Hi Mike,

Thanks for the extra tips.  Yes I am somewhat obsessive with recycling.  With your agent that does the garbage-collection is this an agent written specifically for that purpose or the existing agent that processes your documents?

Thanks.

Alex
