The dashboard's top-users panel resolved a handle for every user with a
quota record, then sorted and truncated to ten. On a hold with ~500 crew
that is ~500 serial identity lookups to render ten rows.
Each lookup goes through the shared identity directory, whose HTTP client
allows 10s per request. One stalled lookup consumed the entire reverse
proxy budget, so the panel returned a partial body and the client hung up
mid-render:
admin/auth.go:161 "Failed to render template"
template=partials/top_users.html
error="write: broken pipe"
"GET /admin/api/top-users?limit=10" - 200 4096B in 10.005s
Sort and truncate first, then resolve only the surviving rows, so the
count is bounded by the limit rather than by hold size. Resolve those
concurrently under a 3s deadline: a slow lookup now degrades to a bare
DID instead of taking the whole request down with it.
The crew tab has the same underlying problem in a different shape, one
lazy-load request per row, and is not addressed here.
