nginx: src/os/unix/ngx_process

annotate src/os/unix/ngx_process_cycle.c @ 7663:7cbf6389194b

Fixed SIGQUIT not removing listening UNIX sockets (closes #753). Listening UNIX sockets were not removed on graceful shutdown, preventing the next runs. The fix is to replace the custom socket closing code in ngx_master_process_cycle() by the ngx_close_listening_sockets() call.
