Bug ID 1196401: Restarting TMM does not restart APM Daemon

Last Modified: Mar 30, 2024

Affected Product(s):
BIG-IP APM(all modules)

Fixed In:
17.1.0, 16.1.4, 15.1.9

Opened: Nov 30, 2022

Severity: 3-Major


Due to asynchronous nature of TMM threads and APM plugin channel threads, a core can trigger when TMM exited and APM Daemon (APMD) is still available with earlier TMM plugin handlers.


Might observe APMD core.


When TMM restarts and APM still has old TMPLUGIN handle (which will become invalid eventually).


Restart APM, when TMM is restarted.

Fix Information

Updated TMM bigstart scripts to restart APMD and related tm_plugin services.
