Could you please provide nginx -V output and full config?  Some 
information about the OS may be intresting too (at least, the 
event method as logged by nginx at "notice" level during startup).

Also it's probably a good idea to check if you are able to 
reproduce the problem with 0.8.31 (if you are using older 
version).
