One day while the lab was in session, I was just playing with stuff and tried executing a fork bomb on the server. The moment I executed the fork bomb, all the 120 machines in the lab became unresponsive, including mine. I didnt realize at that time that they were using the same server for code execution as well as auth server.
Use the Debug feature if a software application hangs the system. The Generate NMI to System button can be used to engage the operating system debugger. Initiate the dump of an unresponsive host if you want to capture the server context. The Virtual Power and Reset privilege is required to generate an NMI. Page 83: Ilo 2 Remote Console
