zabbix-web nginx+PHP-FPM container serves / at ~3-5s baseline with
occasional 6-7s spikes (probe path renders full dashboard via PHP).
kube-probe was killing the container after 3 consecutive 5s-timeout
499s, producing CrashLoopBackOff alert noise even though the app
was serving real traffic fine.
15s timeout absorbs the natural variance; explicit failureThreshold=3
documents the policy (was implicit default).
Closes the firing PodCrashLoopBackOff (zabbix-web) + pending
HTTPServiceSlow/HTTPServiceDegraded alerts. zabbix.iamworkin.lan
remains slow at the application layer (separate work — PHP-FPM
warm-up + Zabbix server "host not found" agent lookup spam need
their own fixes) but the pod restart loop stops.
