GTX's running 3.2 and 3.2.1 have this problem when there are jobs in the 
background. if you have support, call the hotline. if not a temporary fix
follows.

  - edit file /usr/sysgen/master.d/kernel,
	   - change line that reads:
	   int network_processor = 1;
	    to
	   int network_processor = 0;
	   - su to root and cd to /,
	   - type lboot (this will build a new kernel
			called unix.new in the current directory),
	   - mv unix unix.old,
	   - mv unix.new unix,
	   - sync, init 0, then restart the system.

this is in the last issue of the PipeLine.
