Description

Parsers that create a transaction per message can end up in a state where transactions are never being cleaned up. This will happen when only "to_client" traffic is seen, and appears to only affect UDP protocols. Without any "to_server" traffic, the transaction cleanup routine never considers these transactions for cleanup.
