Hi Sunil,

this is no error at all. It just gives you some metrics of young generation garbage collections that have occurred.

Hi,  
But I want it to understand, what does it mean?  
Can you please explore what it says?

It suddenly cam when one system started sending logs to centralized logging and those have huge log size accumulated sometime back.

Hi,
