-- TMM leaks memory in the 'bigip_connection' component. -- Depending on the specific iRule configuration, other components, such as 'tcl' and 'tclrule_pcb', may also leak. -- A 'double flow removal Oops' message may be visible in the tmm and ltm log files. -- 'TCL error' messages may be visible in the ltm log file.
After a prolonged amount of time spent leaking memory, TMM may not be able to fulfil new memory allocations and crash. This results in a traffic interruption, a core file, and a failover on redundant units. Traffic disrupted while TMM restarts.
This issue is known to occur only under rare circumstances in conjunction with specific traffic and iRule configurations.
TMM no longer leaks memory.
