Five 262144-token contexts passed every boot gate (KV 1,350,182 / 5.15x) but left 0 bytes free at runtime: a real client request (995-token prompt, max_tokens=261149, sampling params straight from models.yml) killed Worker_TP1 with torch.OutOfMemoryError 'Tried to allocate 50.00 MiB ... 0 bytes free'. Boot is not proof of runtime survivability. Four slots x 262144 fp8 (KV_BYTES 8,311,013,376/rank) returns ~1.93 GiB per rank for activations/graph capture. Unit: Restart=always instead of on-failure — a runtime worker fault makes vLLM's API server exit clean, so ExecStart returned 0 and on-failure never fired, leaving the endpoint down until a human noticed. Also StartLimitIntervalSec=0 and OOMScoreAdjust=-500.

# context over 3 sessions, TP=2, tiered experts, 131-shard payload) on the
|
|
# 2x R9700 pair, dankserver :7770. 2026-09-29 cutover from the R9V radiance
|
|
# fork (git tag frank-primary-r9v-q8-20260929 is the pre-cutover state; its
|
|
# launcher/shim/setup-state machinery is retired and the state dirs stay on
|
|
# disk as rollback).
|
|
#
|
|
# Same port, same served alias; the harness models.yml id is unchanged.
|
|
# The serve script drives `podman run` directly (the image entrypoint execs
|
|
# `vllm serve`) and then waits on the container. NOTE: that wait can return
|
|
# 0 even when the engine died mid-request (vLLM's API server drains and
|
|
# exits clean on a worker fault), which is why the restart policy is
|
|
# `always` — see the [Service] note.
|
|
#
|
|
# WHY A ROOT UNIT (not a rootless quadlet): the tiered-expert shape pins tens
|
|
# of GiB of host RAM (the expert host slabs, ~20.5 GiB per rank of pinned
|
|
# anonymous memory). Pinned pages are charged against RLIMIT_MEMLOCK; dank's
|
|
# login session on this host carries 8 MiB and a user quadlet is capped by the
|
|
# user manager's own hard limit — raising that means restarting
|
|
# user@1000.service and bouncing every user container on the host. A root unit
|
|
# grants LimitMEMLOCK=infinity to the dank process via PID1, and the image
|
|
# stays in dank's rootless podman storage.
