Symptoms

MRF Diameter remembers details for each request message to assist with routing answer messages. If the answer message is not received, this information is not cleaned up.

Impact

For each unresponded request message, memory is leaked. Eventually the system might run of memory and restart.

Conditions

The server does not respond to a request message with an answer message.

Workaround

None.

Fix Information

The DIAMETER logic will not delete any stale pending request record if it is older than twice the configured transaction timeout (in diameterrouter profile).
