Description (partial)

Detect memory leaks on LC (both on active and standby) after do many times of LCHA. Leaks chunk will show as:
AllocPC  Address  Size  Parent   Name
 2CF54DC 29638274   144 296284D8 (GUARDIAN_IDX_KE)
 2CF54DC 29638314   144 296284D8 (GUARDIAN_IDX_KE)
 2CF54DC 296383B4   144 296284D8 (GUARDIAN_IDX_KE)

Continuously do PRE switchover, LC switchover and linecard 'hw-module' shutdown for many times.
The issue happened in the scenario of:
1. '(no)hw-module shutdown' will cause the modular host to manage SPA failed to set BPI for DS channenls.
2. LC switchover will recover the inner data of BPI to re-set.
3. 'set failure' will cause the inner DB de-queue but missing release. So that the memory leaks happened.
While it happened, only one element (inner data 144 bytes) leaks every time.
