Hey there! I got a weird error during a stress test of SpiceDB, 1 user, 1 thread, so no concurrent requests. ~10k requests no issues, then suddenly SpiceDB stopes answering and I see errors on the SpiceDB side

{
  "level": "error",
  "module": "pgx",
  "args": [],
  "err": "FATAL: query_wait_timeout (SQLSTATE 08P01)",
  "pid": 868501332,
  "sql": "begin isolation level repeatable read read only",
  "time": "2022-11-16T16:11:05Z",
  "message": "Exec"
}

I have 3 instances of SpiceDB running in Kubernetes. Have somebody ever seen this error?
