DB2 FOR LUW / DB2FORLUW / A10 - DB2 | |
Problem description: | |
db2fmp processes may be forced or terminated as part of normal processing. Due to a timing condition, they may miss the request and end up lingering on the system as "unstable" db2fmp processes. Over time the number of such processes may build, consuming excessive system memory, and affect the performance of the system and/or deplete paging space. | |

Local Fix: | |
Leftover unstable db2fmp processes can be identified by running "db2pd -fmp", and finding processes with a value of 0x00000830 for "Flags". They can be terminated using the db2fmpterm command. For example, in the following output, process 33882316 has a Flags value of 0x00000830, and can be terminated by issuing "db2fmpterm 33882316" Address FmpPid Bit Flags ActiveThrd PooledThrd ForcedThrd Active IPCList 0x078000000414D5E0 33882316 64 0x00000830 0 0 0 Yes 0x078000000414FBA0 | |
