Please suggest, how we can tune jvm to avoid such Error. I have already tried with HPjconfig and kernel parameter are up to date.

Looking forward for response.

any chance you can post your glance memory report? and

swapinfo -tam

I need one more information, i have tuned my machine kernel parameter and as well as jvm option as much as possible and i am still trying.
How i can raise a bug on jvm of HP-UX?
