Information in this document applies to any platform.

Symptoms

The shared pool component "hssk hofpa/3" grows - in some cases increased by 3-4 MB a day.

This is supported by queries from v$sgastat and dba_hist_sgastat.

Flushing the shared_pool does not free the memory from "hssk hofpa/3", only a database restart will free the memory.

The increased memory usage can cause shared pool contention and ORA-4031 after some time.
