Yeah bro.....we're following gencon policy....have read some documents on red books.....antha clear ga ardham kaatledhu.

Issue entante.....GC time spent on collection ekkuva time theeskutundhi....where heap utilization is normal. I have analyzed stderr.logs using ISA-GCMV garbage collection and memory visualizer and it was showing AF allocation failure and suggesting to increase nursery heap size.

Need some clarity on GC policies and some analysis concepts under ISA tool. PM me bro if u can explain or help me. Thanks.
