FastL4 connections with late binding enabled typically used for FIX protocol can stall or hang if they are evicted from PVA and not re-offloaded.
Connection may stall.
- Late binding enabled on a FastL4 flow. The flow is not accelerated, and if the flow recieves approximately 50 packets, then it will hang. Captures would show packets ingressing to the BIG-IP and not being forwarded to the peer.
Disable late binding. If late binding cannot be disabled, then disable pva-flow-aging and pva-flow-evict to avoid the issue.
FIX protocol flow works as expected.
