tune Nextcloud Apache/PHP to fix constant crash-looping (50 restarts/6d)
Root cause: Apache prefork with 150 MaxRequestWorkers (each ~220MB RSS)
on SQLite DB causes worker exhaustion + lock contention → Apache hangs →
aggressive liveness probe (3 failures × 10s) kills container.
Fixes:
- Apache: MaxRequestWorkers 150→25, MaxConnectionsPerChild 0→200,
StartServers 5→3 (via ConfigMap mount over mpm_prefork.conf)
- PHP: max_execution_time 0→300s, max_input_time 300s (prevent zombie workers)
- Liveness probe: period 10s→30s, failureThreshold 3→6, timeout 5s→10s
(180s tolerance vs 30s before)
- Readiness probe: period 10s→30s, timeout 5s→10s
