<p class="MsoNormal">Finally figured it out. I enabled debug mode on the error log. It turns out setting the worker_rlimit_nofile in the nginx.conf was not working. On nginx startup it would say “getrlimit(RLIMIT_NOFILE): 1024:4096". I had already checked the
security limits and they were set… I confirmed that the workers were using the worker_rlimit_nofile correctly, but the master was not able to reload correctly.<o:p></o:p></p>
