According to top, it most definitely does not look like a memory issue...more CPU than anything: last pid: 21486; load averages: 30.71, 27.04, 21.48 up 1+18:19:37 11:10:07750 processes: 22 running, 727 sleeping, 1 zombie CPU states: 86.0% user, 0.0% nice, 13.6% system, 0.4% interrupt, 0.0% idle Mem: 662M Active, 948M Inact, 297M Wired, 56M Cache, 199M Buf, 48M Free Swap: 4000M Total, 4000M Free James Smallacombe PlantageNet, Inc.
