Error description
This issue is specific to Db2 running under Windows operating system only and with version 11.1 mod 4 fix pack 4. When a EDU is released from serving an application it will leak a private memory block. Depending on the configuration and number of connections coming in/out the leak might grow rather quickly. The type of blocks leaked will be visible in a "db2fodc -memory" output file "db2pd.memblocks.private". In this file, the persist pool of the private memory will be the main consumer with a large count of blocks: ... Total size for persist pool: 7673057192 bytes (PoolID: 86, SecondID: 0, PoolAddr: 0x000001504C280498) Total size for Private memory set: 7673668136 bytes All memory consumers in Private memory set: PoolAddr PoolID PoolName SecondID TotalSize(Bytes) %Bytes TotalCount %Count LOC File 0x000001504C280498 86 persist 0 7663597408 99.87 216388 99.43 476 4284367586 0x000001504C280498 86 persist 0 6549088 0.09 52 0.02 196 1235720678 0x000001504C280498 86 persist 0 1159264 0.02 490 0.23 244 4283993058 0x000001504C280498 86 persist 0 786432 0.01 6 0.00 5176 745254192 ...
