Hey guys, Nginx crashed 2 times on 2 of my proxy servers... no errors in logs and i cant figure out why the crash took place. I do see from my rrd files that there was about 20mbps of http traffic going to the box at the time of the crash... any ideas? Thanks,

Igor would probably ask at this point for a debug log. If this continues to happen I would compile nginx --with-debug and have a way to log when it crashes if you can. You can limit who triggers debugging by IP too by using debug_connection, otherwise you will have immensely large logfiles, but at least you'd possibly be able to track down the event and have the info Igor would probably be able to pick apart.

I am using nginx as a part of ddos mitigation system so it really pushes all resources to the limit :) Thanks again

If nginx exists on single there is a alert message in error_log.
