APAR status
Closed as program error.
Error description
If the DB2_FMP_COMM_HEAPSZ is set to greater than 1GB size ( ~250,000 pages ), its silently set to a value of ~1GB. In highly concurrent environments where the FMP infrastructure is used extensively ( such as Federation ), this can cause "Out of memory" errors and subsequent crash of the FMP threads. This happens even when the registry var is set to a higher value than 1GB.
