Eventually, all processes have at least one gracefully terminating connection, and then no more new connections are accepted. Same as stated above, I could provoke this situation by reloading Apache. Configuration includes mod_proxy and mod_proxy_wstunnel and a reverse proxy configuration like this: RewriteEngine on RewriteCond %{HTTP:Upgrade} =websocket [NC] RewriteRule /(.*) ws://127.0.0.1:8888/$1 [P,L] RewriteRule /(.*) http://127.0.0.1:8888/$1 [P,L] Having attached the debugger to a process containing one such gracefully stopping connection, I got the following stack trace for the specific thread: Thread 26 (Thread 0x7f7e02bcd700 (LWP 320536)): #0 0x00007f7e182895ce in epoll_wait (epfd=28, events=0x7f7e157a55a8, maxevents=2, timeout=-1) at ../sysdeps/unix/sysv/linux/epoll_wait.c:30 #1 0x00007f7e183a178e in ??
