No there isn't. My first thought was a DOS attack, so I checked the log. I don't see any one IP or URL the jumps out. Also the traffic seems steady right up to when it locks up. You can see it on ganglia. The graph goes from the bottom to over the top in 5 minutes. The only thing I saw the shocked me, was watching top. You can see the number of apache processes almost double in an instant.
There was an increase in the total traffic for the day. On the 16th the total hits was 70890 and on the 17th it went to 113208.
