  • 'view-pool-timeout' (warning) Dirty output was returned after failing to acquire a work lock (got QUEUE_FULL or TIMEOUT from PoolCounter).
  • 'pool-queuefull' (error) unable to acquire work lock, and no cached content found.
  • 'pool-timeout' (error) unable to acquire work lock, and no cached content found.
  • 'pool-servererror' (error) PoolCounterWork failed due to a lock service error.
