[SVE1] Possible memory leak in chip-tool

[doru91]

Problem

After successfully commissioning with the 4th administrator, chip-tool reports:

[1657625195.034286][3459:3459] CHIP:SPT: VerifyOrDie failure at ../../examples/chip-tool/third_party/connectedhomeip/src/lib/support/Pool.h:317: Allocated() == 0

This is 100% reproductible on NXP platform.
chip_tool_logs_4th_admin.txt
dut_logs_4th_admin.txt

Also attached the entire logs on the DUT and chip-tool side.

The check seems to fail at an assert all memory has been freed by the time Pool is deallocated, so we seem to leak a pool object.

Maybe we could compare logs from the 1,2,3 logs and the 4th one. My guess is that some error condition does not fee up its data. Looking at errors I see

[1657625194.992609][3459:3464] CHIP:EM: OnMessageReceived failed, err = ../../examples/chip-tool/third_party/connectedhomeip/src/me                           ssaging/ExchangeMgr.cpp:274: CHIP Error 0x00000070: Unsolicited msg with originator bit clear

however commissioning generally looks ok.

Could you check which pool gets this? At least that should narrow down figuring out what object leaks.

Removed cert blocker: memory leaks are likely not cert blockers.

Or if they are, please add a justification (like cert test does the 4 executions and because app crashes, certification fails)

@cjandhyala - please see above: is this actually a cert blocker (if so please explain and re-add the tag) or was my removal of cert blocker tag correct?
