What could be causing this crash ? also is --with-http_mp4_module stable
enough to be replace h264.code-shop module.

Any help to fix this would be greatly appreciated.

First of all I would recommend to test if you are able to
reproduce the problem without 3rd party modules compiled in.

General debugging hints may be found here:

http://wiki.nginx.org/Debugging

The mp4 module is stable enough and has no known problems.

Hello,

Thanks Maxim for looking into my issue.

I recompiled nginx with no 3rd party module & debugging enabled.

there is no nginx.core file found in /home/core/ , thats the path
specified
in nginx.conf

but i still keep seeing

there is no nginx.core file found in /home/core/ , thats the path specified
in nginx.conf

Make sure:

  • /home/core/ is writable (chmod a+w)
  • ulimit is configured correctly
  • fs.suid_dumpable is ok?

You can read more about it here:

It looks like you forgot to restart (or upgrade binary on the
fly), and old nginx with 3rd party modules is still running.
