Issue/Introduction

Instability situation facing in the DX Application Performance Management.
Intermittently it is possible to see that the instability kept happening during the day and the environment access gets unavailable for 5 minutes. 
After that, the environment normalizes until it happens again. There are no steps taken to correct the issue, the issue gets resolved own its own. The issue is occurring when working within APM as it is mainly used for APM. 
Also found that some pods were restarting, but we couldn't identify the root cause. 

Environment
