Hello All,
We are running WMB 6104 on AIX 5.3. we are seeing issues with a particular framework message flows consuming very high memory(swap) utilization for the EG's that have these flows. These flows are very large with 150 nodes per each flow and 15 to 20 instances of each flow running in every EG and almost 10 of such flows. We tried to isolate the flows to their own EG's but they are consuming equally high memory even in a scenario where we have one such flow per EG.

I know it is a vague question to ask for the reason for the high memory, because without seeing the code no one can say why they are consuming so. But my reason for posting here is to know if anyone else has seen similar issues in their envs and what might a few possibilities for high memory. May be if possible a few references from IBM docs or anywhere else which can point us to similar situations.

FYI: we opened a PMR and worked for 3 months with IBM hursely folks and they have asked us to set an env variable MQSI_FREE_MASTER_PARSER, initially for a few days we were comfortable with the memory, but looks like the problem is back after the appication area made some code changes.
One such change to use File input node sunsetting the MBFE.

Thanks in advance.
