The GenericMessage filter does not have a configurable limit to the number of messages that can be received.
If too many messages are queued, the system may exceed an internal count which could lead to a core.
If a message is waiting for an asynchronous iRule operation during a GENERICMESSAGE_INGRESS or GENERICMESSAGE_EGRESS iRule event, new messages are placed in either the ingress or egress queue. As the number of messages increase, more memory is required.
None.
The existing max_pending_messages attribute of the message router profile is used to limit the size of the queues.
