The memory usage on our RHEL4 WHM server shot up from no more than 1.8GB to 8GB a few days ago and it's stayed up there.
Attached are images showing the trends for the last month and the last 24 hours or so.
The usual utilities (top, ps, etc.) don't show any processes using more than 130MB individually. Restarted many daemons individually with no significant drop in memory usage. Rebooted the server at 5am today and the usage was back up to the same level again within 1.5 hours.
Any ideas for causes or tools to investigate further?
