Last week nds02ps crashed a bit, and had trouble crashing on automatic restart. I think the issue was that when the ndps broker and manager were loading too soon after startup, we ran out of memory or cpu or karma and the box would crash.
I've added the command DELAY 120 just before loading the broker/manager, so we should wait 2 full minutes after a reboot to actually start the print system. Hopefully, this delay will help the box survive a reboot.
