TCP analytics does not release memory when a specific sequence of packets is observed, and memory usage increases as more such flows occur.
Main memory occupied by TCP analytics is not released which might lead to memory exhaustion on the BIG-IP system.
-- A TCP analytics profile is configured to collect clientside/serverside analytics data. -- AVR is provisioned. -- FastL4 and HTTP profiles are configured. -- A specific sequence of packets (on the serverside) occurs.
Turn off collecting TCP analytics data for the virtual server.
TCP analytics now releases resources properly.
