Issue regarding the Garbage collector

[former_member203029]

Hi guys, Currently I am facing an issue regarding the Garbage collector , seems like it's running for a longer time than usual. Checked the XMX and XMS parameters ; paging's is maintained for 50 GB which seems to be enough, Upon checking the MMC and blogs came to know the GC is running longer time than required. As an result the Garbage Collector is running more time that required and producing heap dumps. I would like to know how can i resolve the issue. Thanks & Regards, Kaushik G

Hi Kaushik,

Do few things -

1st - Take thread dumps of your server nodes

2nd - Trigger heap dump of your server nodes

3rd, Download MAT and TDA tool( depending on NW release)

If GC is running high, you need to check why this is high - possible problems, like memory leaks or bad java codes or less configured heap areas.

Looks in logs and check above two dumps.

Hi Kaushik,

I would request you to checks default trace/logs which may give you some error information why heap dumps are generating.

also analyse heap dump with memory analyzer tool to understand issue.

Thanks,
