TMM may leak memory when plugins are in use and the plugin is re-initialized (typically due to configuration changes). In rare cases, memory corruption may occur causing TMM to restart.
The memory leakage generally occurs infrequently and at a rate that TMM operations are not affected. However, when memory corruption occurs, a traffic interruption may occur due to TMM restarting.
Plugin-based functionality configured (ASM, APM, etc.) and configuration changes occur.
No workaround except disabling plugin-based functionality (such as ASM, APM, etc.).
TMM now properly manages plugin memory, and no longer leaks or corrupts this memory.
