Symptoms

Assigning 'after' object to a variable prevents the release of the 'after' object and its related connflow object, resulting in a memory leak for 'connflow', 'tcl (variable)', 'tclrule_pcb', and 'filter (variable)'.

Impact

TMM crash or TMM memory usage increases.

Conditions

This occurs when using the 'after' iRule command and assigning it to a variable.

Workaround

Unset the variable containing the 'after' object, for example: when HTTP_REQUEST priority 800 { set SCRIPT_ID [\ after $static::one_second { log local0. "$LOG_MSG" } \ ] } when CLIENT_CLOSED { unset SCRIPT_ID }

Fix Information

Assigning 'after' object to a variable no longer causes memory leaks.
