Problembeschreibung: | |
Application Heap consuming memory and causing out of memory errors when instance is running with intra-partition parallelism and plan chosen is rebalancing rows between SMP subagents (REBAL will be seen in explain). The problem is triggered by a memory leak in the rebalancer, which can be identified with the following relevant lines of a "db2pd -memb" output: ... Memory blocks sorted by size for apph pool: PoolID PoolName TotalSize(Bytes) TotalCount LOC File 1 apph 1142997347 1145749 **** 1984253944 Memory blocks sorted by size for apph pool: PoolID PoolName TotalSize(Bytes) TotalCount LOC File 1 apph 2189465388 2177435 **** 1984253944 Memory blocks sorted by size for apph pool: PoolID PoolName TotalSize(Bytes) TotalCount LOC File 1 apph 2049430557 2043158 **** 1984253944 All memory consumers in Appl memory set: PoolID PoolName TotalSize(Bytes) %Bytes TotalCount %Count LOC File 1 apph 2189465388 38.33 2177435 0.66 **** 1984253944 1 apph 2049430557 35.88 2043158 0.62 **** 1984253944 1 apph 1142997347 20.01 1145749 0.35 **** 1984253944 | |
