If a plugin is disabled, the mechanism to recover the memory it has allocated related to a traffic flow when the traffic flow ends is subverted, so that memory leaks.
Memory used by the tmm process increases, until, eventually, the tmm process restarts.
This can happen when plugins are programmatically disabled, for example, by an iRule.
Avoid disabling plugins programmatically. Doing so might not be practical.
Disabling plugins programmatically is now supported, and TMM memory use does not increase with traffic that would otherwise involve those plugins.
