In general we configure MySQL and Tomcat (java) to take a significant % of the total system memory to increase caching. So it's normal to see a large memory footprint for these when you've got so much RAM on the machine.
Are there any other applications running on the machine. What's the CPU usage like(any IO wait?)? What operations do you see this on? How many user's are on the system? Are they all using the web interface?
Anything in the logs? |
