nginx reload not working; creates orphan yet active worker

[0x7f]

Same issue here (nginx 1.6.2 as well). Let me know if you need any additional information.

[yaoweibin]

Could you show me any error information in the error.log?

Hello! Nginx's error logs don't show any error on reload, both in the cases when the reload works as expected, and when it doesn't.

Note that the problem always happens at the second reload call (after the nginx startup).

Hello.
I have same issue.
After reload, master process disappeared, and workers still run.

In strace -p 28779 (some worker pid) I see many call like:

epoll_wait(42, {}, 512, 5) = 0
epoll_wait(42, {}, 512, 5) = 0
epoll_wait(42, {}, 512, 5) = 0
epoll_wait(42, {}, 512, 5) = 0
epoll_wait(42, {}, 512, 5) = 0
epoll_wait(42, {}, 512, 5) = 0
epoll_wait(42, {}, 512, 5) = 0
epoll_wait(42, {}, 512, 5) = 0

And this messages appear very very quickly. Normally they appear approximately once per second.

On nginx 1.8.0, the problem doesn't happen anymore. It used to happen on previous version; the O/S is the same.

same issue on nginx1.8.0, with check module0.3.0, patch version is check_1.7.2+.patch.

Then download the newest master zip package, and change the patch version to check_1.7.5+.patch. reload works now .
