I'm looking for any hints/pointers that would help me detect why the box decided to shutdown. Perhaps someone with similar experience? This is from 'last' command: shutdown ~ Sun Nov 18 03:12 This is from 'messages' log: Nov 18 03:12:26 my_machine syslogd: exiting on signal 15 The fact that at least this information was logged suggest it was not a Very Bad hardware crash, especially since the machine booted O.K. when turned back on and is up now, so it seems it might be software-related. I checked ipfw log, apache log, postfix log and other less relevant logs to find anything suspicious, but nothing was found. I also have monitoring software (munin) which shows absolutely no suspicious activity (regarding cpu, load, memory, network usage...) at the time of shutdown. What would be your guess - software, hardware, security issue... - as to what happened? Thanks and regards, -- Nino
