Description (partial)

Symptom:
A memory leak in the aclmgr process is seen. After checking the memory we see the following is leaking:

Lib ID: 0x1
Mem stats for UUID : Non mtrack users(0) Max types: 177
--------------------------------------------------------------------------------
TYPE NAME                                       ALLOCS                 BYTES
                                         CURR      MAX        CURR       MAX

   2 [r-xp]/isan/plugin/0/isan/bin/aclmgr 5285752 5285756  363171903  363181841

The leak will eventually lead to a process crash and could result in a system reload due to a HAP Reset.

Conditions:
This issue is seen while a script dynamically modifies ACLs. We are still looking into the exact conditions of this issue.

This leak happens when user is using "configure session" to configure ACLs.
It is also seen if user configures time-ranges.
