Have Risc6000 with 5.1L amd 4.3.1 Operating system. On different days at differnet locations I get a partial reboot at the CPU.Sometimes the console monitor stops at "cron may not be running". I can turn monitor off and back on and find that it has really booted up. Other times I have to reset the machine to get it to fully boot up. Any suggestions as to what could be causing this partial reboot?
