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.
