Hey,
I can also reproduce it on -current and firefox-esr. It is related to the
timeout handling, but I don't know a fix yet.
A faster way to reproduce it is to add to httpd.conf:
server "*" {
connection {
request timeout 5
}
...
}
Then do a single request (no need to spam it) and wait 5 seconds.
Then (when run with httpd -d -vv) a line appears:
server *, client 1 (1 active), 127.0.0.1:43314 -> 127.0.0.1:6970,
timeout (408 Request Timeout)

Kind regards,
Hiltjo
