Dead/hanging threads on 1.13.0

What happened?

I am not sure how to properly describe this, to be honest. Since I updated FrankenPHP to 1.13.0, I've been experiencing some performance issues on the server. Usually intermittent, but matomo-org/device-detector#8404 is a recurring issue, which may be related.. It may not be FrankenPHP's (or Caddy's) issue necessarily, since I am also in progress of migrating to Symfony and the update coincided with a batch of changes for that as well, but I noticed something that suggests that it is likely FrankenPHP.

curl -s localhost:2019/metrics | grep frankenphp_

frankenphp_queue_depth 2622
# HELP frankenphp_total_threads Total number of PHP threads
# TYPE frankenphp_total_threads gauge
frankenphp_total_threads 24

notice how the number of busy threads is abnormally high and is a combination of total threads and queued threads. In my understanding it should be the number of actually working threads, though. But maybe I am wrong. On the other hand I've seen it grow to over 300000 threads (not a mistype) and even have negative values. After restart, it works completely fine for a couple of days, although the queue itself still grows (quite expected, bots are insane even with CrowdSec and rate-limiting getting an average of 50 session per second which do reach PHP).

I do not have any proof, but something tells me, that threads are not being handled properly. Any suggestions on what I can do to try to debug this?

Relevant log output

Yeah the frankenphp_busy_threads metric is a bit misleading as it also counts queued requests. Definitely would make sense to exclude queued requests as this has confused other people before.

Do you see anything else in your error logs? Are requests timing out? If your queue depth really grows this large, I'd maybe also advice setting a max_wait_time to time out requests when the server is truly overburdened. Also, you can try setting a higher max_threads to see how traffic fluctuates.

frankenphp {
    max_wait_time 15s
    max_threads 100
}

You can also try upgrading to 1.13.1, which fixes some HTTP2 issues I think.

Updated prod to 1.13.1, will monitor the situation.
