load average: 5.00, 5.00, 5.00

Any time you have a whole number load average, it usually means you've got some stuck processes. What do "top" and "ps aux" show you?

If a process runs constantly with no breaks, it'll add 1 to load average. Load average also increases if there are bottlenecks, like a bunch of processes queued up waiting to read/write to disk.
