I am looking after a server that has 6GB of RAM. There is a JAVA binary running that is using 1.8GB RAM, but nothing else is using anything near that, but I am seeing a constant 85%+ usage of physical memory.
The other processes don't add up to the difference so where else can I see what is using the memory?
I've never seen this before...
UPDATE 1: During my research I have discovered that SQL server can use more memory than it shows it is using in Task Manager. My box is running MySQL so I am wondering if a similar thing happens here?
