Thanks for the recommendation, but we already identified and addressed the issues with GC pauses in JVM, and now we could not find any long gc activity during the time of node failure due to network segmentation. (please find the attached screenshot of GC activity from dynatrace agent).
>From the screenshot, there is only young generation gc collection and that too < 100ms. We can still enable gc logs and i strongly suspect the issue is beyond jvm pauses.
