Hey Igor,

Nginx process crashed without leaving any traces in the system logs or error.log
Im going to rebuild with debug in there but I still an more sure why
it crashed (2 different boxes... both nginx crashed under 20mbps of
load / 8k-10k request/sec while the other 8 boxes did not)

Unfortunately I have not had much time to resume troubleshooting but
hope to start again in a few days
