Basic debugging when you have a problem:
Look at the machine:
Look at processes
Look at users
See what's going on with the machine.
The first thing you could have noticed was a very high
load average. Oh, it's (dangerously), running ftpd.
Offline, I suggested raising the queueLA and refuseLA,
but really: Move FTP of the freaking machine.
