nginx reload not working, restart creates orphan yet active worker

[groknaut]

unfortunately at this time our site relies on nginx_upstream_module. not
sure if/when i'll have time to rebuild sans those modules and try to
repro. in the meantime, i'm going to add configuration to allow nginx to
dump core, and see if the module author, yaoweibin, has any insight.

of course if you can offer help i'd love to have it.

thanks
