Opened: Jul 17, 2015 Severity: 2-Critical
When running an irule that has PEM::session info commands, it was observed that the memory consumption by the PEM module kept going up till and the system eventually ran out of memory.
System runs out of memory.
Create an irule that has PEM::session info commands that run asynchronously and attach it to one of the virtuals in use.
None
The memory leak while executing the commands - <PEM::session info /PEM::subscriber info/PEM::session config policy/PEM::subscriber config policy> has been fixed. The leak only occurs when these commands run asynchronously.
