Error description
OMEGAMON DB2 V510 uses subpool 129 key 7 to build cell pools for XCF communication between LPARs. The storage is obtained by KO2ZTOPB, the job step TCB. After the XCF communication is performed by a daughter TCB, the cell pool is released. However the storage is not released due to the characteristics of subpool 129; the storage is owned by the job step TCB and must be freed by the job step TCB. This issue becomes very apparent in an environment that has a high volume of session create / session terminate activity. Session create / terminate activity is evidenced by this sequence of message ids OMV006I KO2X0451I OMV994I OMV996I KO2X0453I The result of this storage issue can also be seen in various storage related abends such as C78, 878, 80A Also present in the joblog are a high volume of messages KO2O1941E EXCHANGE LAYER CALL - RETURN CODE 00000008 (CIFIEXCH) KO2O1942E EXCHANGE LAYER CALL - REASON CODE 0000007B (CIFIEXCH) Other messages that might be seen are FPEV0003S DBP1 GETMAIN 83 FAILED.

Local fix
Monitor storage usage in sp129 key 7 that belongs to TCB KO2ZTOPB. Cycle the OMEGAMON DB2 collector task to release the storage as needed
