The pretix image derives its worker count as `2 * $(nproc)`, which counts the host's cores rather than the container's share. On a twenty-core host that is forty gunicorn workers inside a 2g memory limit and a 1024 pid limit, and the container is OOM-killed before it serves a request: docker reports exit 137 with OOMKilled true, and the log shows workers taken by SIGKILL. NUM_WORKERS now applies upstream's own formula to the CPUs the service declares, with a floor of two so a fractional allocation cannot round to none. PRETIX_WEB_CONCURRENCY and PRETIX_WORKER_THREADS were already set but the launcher reads neither for the worker count; they are pretix application settings, so the role was configuring something that never influenced the process count. After the change pretix comes up healthy and stays up across three subsequent full runs, and its MCP contract probe passes in two of them.
