+Stability test plan was triggered for 72 hours. There were no failures during the 72 hours test.

- As part of the OOM deployment, another APEX-PDP pod is spun up with the pdpGroup name specified as 'sampleGroup'.
- After creating the new group called 'sampleGroup' as part of the test, a time delay of 2 minutes is added,
- so that the pdp is registered to the newly created group.
- This has resulted in a spike in the Average time taken per request. But this is required to make proper assertions,
- and also for the consolidated health check.

- There were some failures during the 72 hour stability tests. These tests were caused by the apex-pdp pods restarting
- intermitently due to limited resources in our testing environment. The second apex instance was configured as a
- replica of the apex-pdp pod and therefore, when it restarted, registered to the "defaultGroup" as the configuration
- was taken from the original apex-pdp pod. This meant a manual change whenever the pods restarted to make apex-pdp-"2"
- register with the "sampleGroup".
- When both pods were running as expected, no errors relating to the pap functionality were observed. These errors are
- strictly caused by the environment setup and not by pap.
+ There were no failures during the 72 hours test.

+- Usage of counters (simulating each user) to create different pdpGroups, update their state and later delete them.
+- Removed the tests to deploy policies to newly created groups as this will need a larger setup with multiple pdps registered to each group, which will also slow down the performance test with the time needed for registration process etc.
+- Usage of counters (simulating each user) to create different drools policies and deploy them to defaultGroup.
