There is a gradual memory leak in TMM when iRules are triggered with an AFM ACL rule. Eventually, over a period of time, this may cause TMM to start running out of memory and sweeper may start killing existing connections to recover from this.
Memory leak in TMM eventually leading to memory pressure that may result in TMM dropping existing connections.
AFM is enabled and there is at least 1 AFM ACL rule configured with an iRule on it.
This issue has no workaround at this time.
Previously when an iRule was triggered by an AFM firewall rule, a memory leak could occur. This has been fixed.
