The BIG-IP system running RSS DAG hash attempts to reuse ports while pool members remain in a TIME_WAIT state and are unable to process new connections.
Traffic throughput may be degraded.
This issue occurs when all of the following conditions are met: -- You are running on a BIG-IP platform using RSS DAG hash, for instance, z100 and 2000 or 4000 series hardware platform. -- You have the FastL4 profile associated with a virtual server. -- The virtual server is configured with source-port preserve.
Set source-port to change.
Platforms running RSS DAG hash now reuse source port at the correct rate when virtual server sets source-port preserve.
