Can you please give me the following information:

  • platform?
  • architecture?
  • do you have the nginx upload module compiled in?

If you are running the nginx upload module, make sure you use the latest GITversion as there is a crasher in 2.0.10.

Please capture a core file of a debug
build of nginx (make sure you compile with --with-debug and that the
executable is not stripped).

On linux, you can do something like this to enable core dumps:
ulimit -c unlimited # in your nginx startup script
mkdir -p /var/lib/core
chmod 1733 /var/lib/core
echo '/var/lib/core/core.%e.%p.%t' > /proc/sys/kernel/core_pattern

then start your debug nginx.

Then as soon as you get a core:

$ gdb /usr/sbin/nginx /path/to/core
gdb> bt full

And send me the output for analysis.

Thanks,
