$ grep -rl epoll_wait nginx-1.21.5<br>
nginx-1.21.5/src/http/ngx_http_upstream.c<br>

I'd probably start there.<br></blockquote><div><br></div><div>Yeah. Thanks. In line 800 of nginx-1.21.5/src/event/modules/ngx_epoll_module.c it says events = epoll_wait(ep, event_list, (int) nevents, timer); Thus the variable timer is used. Line 123 and 124 seem to give the definition of the function call which supplies the timer variable static ngx_int_t ngx_epoll_process_events(ngx_cycle_t *cycle, ngx_msec_t timer,</div> ngx_uint_t flags);</div><div class="gmail_quote"><br></div><div class="gmail_quote">So then I did:</div><div class="gmail_quote"><br></div><div class="gmail_quote">grep -rl ngx_epoll_process_events nginx-1.21.5</div><div class="gmail_quote"><br></div><div class="gmail_quote">and got:</div><div class="gmail_quote"><br></div><div class="gmail_quote">nginx-1.21.5/src/event/modules/ngx_epoll_module.c</div><div class="gmail_quote"><br></div><div class="gmail_quote">I can't find any calls to that function in that file.
