Tmm crashes while passing IPv4-to-IPv6 traffic over FastL4.
All traffic is disrupted while the TMM restarts.
-- A FastL4 virtual server translates between IPv4 and IPv6. -- Fragment reassembly is not enabled in the FastL4 profile. -- A feature requiring asynchronous completion is configured including: asynchronous irules on LB events (LB_SELECTED, LB_FAILED, LB_PERSIST_DOWN, LB_QUEUED, SA_PICKED), persistence, sessiondb operations, HA, virtual rate limiting.
Configure the FastL4 profile to always reassemble fragments.
