X_SCRAPE_PAGE_CRASHED
Means
the renderer process died
Typical cause
terminal, and it is the one liveness fault that is. A dead renderer takes its tab's state with it, so a re-run of a half-submitted form is the incident rather than the recovery. Out of memory far more often than a bug
Fix
lower concurrency: on the scrape() definition, or raise the container memory limit in docker-compose.prod.yml
