[Pairing Reliability] #6 Failure: Commissioning failed with src/lib/address_resolve/AddressResolve_DefaultImpl.cpp:119: CHIP Error 0x00000032: Timeout

[Saravana-kr22]

Description:
I have used python controller to run a stress test on my RPI sample dut (all-clusters-app) on Pair-Unpair test scenario for 10,000 iterations. The test passed in iteration 8022 without any error but the iteration 8023 is Failed to commission the dut during FindOperational step with the below traceback error

Traceback (most recent call last):

GitHub hash of the SDK that was being used: 3718e99

Platform
controller - python controller running on raspi,
DUT - all-cluster-app running on raspi

Provisioned using on-network

Platform Version(s)
RPI-4, 8GB RAM

Test Scenario

1. Pair/Provision the DUT (All-cluster-app running on raspi) using on-network
2. Read device information after the device is provisioned
3. sleep for 2 secs
4. Unpair the DUT (i.e. removing the fabric)
5. factory reset the DUT
6. repeat step1 - 6 for 10,000 iterations
