Symptoms

When tmsh is used to view session information, memory will leak on each request to pull the session information from tmm. This is a small leak but can be significant issue when all sessions are examined or the sessions are examined multiple times in a short time interval.

Impact

Memory will leak in tmm daemons. This affects all modules that use tmm.

Conditions

when using show /apm access-info all-properties

Workaround

The only workaround is not to use the mcp interface by tmm daemon, or to restart the tmms periodically after using the interface multiple times.

Fix Information

Accessing APM session variables via tmsh (e.g., 'tmsh show /apm access-info all-properties') no longer causes a small TMM memory leak.
