We had two servers setup and one of the servers seemed to always lock up. Lock up is defined as all services including the Linux OS itself not accessible. The server is pingable, but the screen is completely black and typing on the keyboard made no difference. I always thought it was hardware related; therefore, I transferred it to a new box and it did the same. I also ran a test and determined that when Nagios was off, the lock up would never occur. I just recently installed a development box and been testing Nagios 2.03b. Every once in a while, the same lock up happens and the only thing can do is a POWER RESET. Has anyone experienced similar occurrence? The only thing I can think of is that all the boxes I had this happen to SENDMAIL was turned off. I run an hourly routine to clear the ClientMailQueue. SENMAIL is turned off so I don't get two pages for every device. Any advice would be appreciated. Thank you. R.
