Forum: NGINX worker process (cache manager process) exiting on signal 11

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! :)

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! :)

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

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

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

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.
