8.2. FP10 win32

I have a productive server and time to time have a trouble with:

db2diag.log

Insufficient memory available for IPC communication with the db2fmp
process. Use the DB2_FMP_COMM_HEAPSZ registry variable to adjust the
amount of memory available for fenced routines.

Current settings DB2_FMP_COMM_HEAPSZ=80000 ( equal 320Mb).

We have some ole/c/sql procedures and functions. And federated objects
too.

I think it's memory leak but I have no idea how I can catch initiator
on productive system.

Help me,
AP
