What the message means

Apache accepts the connection but doesn't return a full HTTP response before the scoring engine's timeout. Common causes: overloaded worker pool, slow backend (PHP / DB), infinite redirect loop, or a script stuck in a loop.

Why the service is down

MaxRequestWorkers exhausted (all Apache workers tied up).
Backend DB (MySQL/Postgres) slow or locked.
PHP process is stuck in a long query.
Infinite redirect: app redirecting to itself.

Commands in order

1. 1. How many Apache workers busy?

ps aux | grep -c '[a]pache2' ; echo ; apachectl status 2>/dev/null || curl -s http://localhost/server-status?auto 2>/dev/null

Expect

Worker count below MaxRequestWorkers

Interpret and next

If at max: tune `MaxRequestWorkers` higher, or find what's holding workers.
2. 2. What does the slow endpoint return locally?

time curl -s -o /dev/null -w '%{http_code} %{time_total}\n' http://localhost/

Expect

HTTP 200 or 302 in under 1 second

Interpret and next

Slow or hung = the app itself is the problem, not Apache.
3. 3. Check for redirect loops

curl -s -L -o /dev/null -w '%{num_redirects} %{url_effective}\n' http://localhost/

Expect

0 or 1 redirect, ending at a stable URL

Interpret and next

Many redirects = fix the app config (often WordPress siteurl).
4. 4. Check DB responsiveness

time psql -U torch_bearer -d db -c 'SELECT 1;' 2>&1

Expect

Under 100ms

Interpret and next

Slow = DB overloaded. Restart Postgres, check for runaway queries.
5. 5. Nuclear: restart Apache

systemctl restart apache2

Expect

Service restarted; requests processing again

Interpret and next

This resets worker count. use when the student can't find the root cause quickly.

Decision tree

Answer each question to route to the right fix.

Q: Does `curl http://localhost/` return quickly (<1s)?

Yes: Network/firewall problem between Apache and scoring engine.

No:

Q: Are Apache workers pegged?

Yes: Find slow query/script; restart Apache as stopgap.

No: Check DB + app logs for stuck jobs.
