Not sure if this is the appropriate forum for this, seemed as good as any. So my vps went down last night and when I contacted the host they said I had an unwanted process running that took up too much load. So clearly I have no idea to figure out what happened. Is there any log somewhere that I can check out to try to pinpoint what exactly happened? Also, is there anything I can set up to alert me to something that's taking up a ton of load on the system? The vps is back up and I don't see any processes that look out of the ordinary, and nothing is using crazy cpu cycles. I did notice that I was running nginx 1.7.1, I'm about to update that to 1.7.2. I'm running 1.2.3-eva2000.06 which was most recently downloaded on June 6th. I also noticed that I'm running Sendmail. Since I'm using godaddy for my email can I assume that it's safe (and smart?) to turn sendmail off entirey using yum remove sendmail?
