Is it really the auth master process that fails?

Both of these lookups should be done by auth-worker processes. So why is it the
auth process that complains?
Anyway .. if the problem really is auth-worker and this is only a logging
problem (I would have expected auth-worker: prefix in log lines), then the
solution is simple. Just restart the auth-worker processes every 1000 lookups:
service auth-worker {
service_count = 1000
}
