Operating Systems Linux Red Hat Java process showing high virtual memory Post 302965373 by Don Cragun on Thursday 28th of January 2016 01:52:23 AM

I'm sorry, but knowing that a single process is showing high virtual memory utilization and is showing comparatively lesser virtual memory consumption seems to imply that two people looking at the same process see it's memory consumption differently. My crystal ball isn't seeing anything obvious to suggest which observer might be correct (if either observer is correct), nor is it able to suggest what to investigate to substantiate either claim.

If we could see the code, we might be able to suggest conditions under which it might use a lot of memory.

If we can't see the code, we can make a lot of assumptions that might or might not apply to some process no matter what language is used to write that process? If we can't see the code, can't see anything other than a conflicting statement about memory usage, and have no idea what the process is doing; there is absolutely no way that tell you what, if anything, is wrong with your code.
