When system is under heavy load, aggregation of statistics tables in the database sometimes takes too much time and watchdog is triggered. When that happens, watchdog aborts the application and produces a core file.

Impact

System produces monpd core file, when no real crash occurs.

Conditions

-- System under heavy load. -- Setting and resetting DoS profile on virtual servers. -- Using AVR. -- Displaying aggregated statistics.

Workaround

None.

Fix Information

Watchdog trigger no longer creates core by default under these conditions.
