Worker process (cache manager process) exiting on signal 11

Server NGINX
1

I’ve compiled nginx 1.3.11 on my RaspberryPI (512MB) running Debian
Wheezy/ARM, and all appears to be quite okay, that is until nginx is
getting
fired up, then it’s aborting with some error message.

Are you able to reproduce the problem without 3rd party modules?

If yes, please follow the instructions here to obtain a coredump
and a backtrace:

Just re-added
“–add-module=/data/src/nginx/modules/nginx-upload-progress-module” and
it’s
still working! :slight_smile:

Re-activating this module
“–add-module=/data/src/nginx/modules/nginx-rtmp-module” causes the
signal
11 terminations

That is, I’ve de-activated all 3rd party modules, re-compiled nginx
(1.3.12), and everything was fine!

Then, next iteration, adding the upload progress module again,
re-compile,
test, cool! :slight_smile:

Re-activating “–add-module=/data/src/nginx/modules/lua-nginx-module”
works,
too!

Finally re-added “–add-module=/data/src/nginx/modules/ngx_devel_kit”
and
all is peachy!

So apparently there’s some issue with the rtmp module.

Re-adding " --add-module=/data/src/nginx/modules/ngx_auto_lib" also
works
perfectly fine!
