Re: [Mojolicious] Troubleshooting Hypnotoad Workers
I'm not sure is this problem related to mine, but I had been having
troubles with hypnotoad before figured out why my site is unresponsive
for 10 seconds in peaks (500-1000 reqs per sec) from time to time.
Changing some defaults worked for me and I decided to stop digging
further, but I can confirm that somewhere a heisenbug is sitting in the
hypnotoad.
multi_accept = 500, (instead of 100)
accepts = 100_000, (instead of default 100)
graceful_timeout = 2, (instead of 15)
Maybe this will help you
I've got an app that is served up by Hypnotoad, with no reverse
proxy.It has 15 workers, with 2 clients allowed apiece. The app is
launched via hypnotoad in foreground mode, as it is being run
underneath a superdaemon service manager.
I am seeing the following in the log/production.log:
|[Wed Apr 1 16:28:12 2015] [error] Worker 119914 has no heartbeat, restarting.

The workers are killed, however, the workers are never restarted.
When I run an strace, the manager process appears to be valiantly
trying to kill the (now expired) workers:

restart_syscall(... resuming interrupted call ...) = 0
kill(119906, SIGKILL) = 0

How can I troubleshoot this further to determine:
1. Why does Hypnotoad think it still needs to kill non-existent
processes?
2. Why isn't it starting new ones?

[Mojolicious] Re: Troubleshooting Hypnotoad Workers
Sounds like you have very bad code running... Do you have a reverse proxy
infront of hypnotoad? If you have nginx, I would probably count how many
499, 500, 502 and 504 you got in the access log, compared to 200. I suspect
the number is very high.
About no
heartbeat: https://metacpan.org/pod/Mojo::Server::Prefork#heartbeat_interval
So, if your worker are doing some blocking work for more than 20 seconds
(default), the manager (parent hypnotoad process) will kill the child
process. And by restarted it means killing a child and starting a new one
to do the same task.
