|Title||Exponential backoff looks like failure|
|Assigned user||Nick Barnes|
|Description||When a replicator poll fails, the replicator "backs off", doubling the period between polls. This is to prevent an e-mail deluge (job000215). If polls continue to fail, the poll period gets very long, and once it gets more than a day or so the replicator appears to have stopped. There isn't any indication of this back-off in the poll failure message, and an administrator who forgets the way the exponential back-off works might well think that the replicator had stalled entirely . This was, in fact, job000482.|
|Analysis||1. Stop doubling once the poll period gets to a day or so.|
2. State, near the top of the poll failure message, the new poll period and expected next polling time.
3. Also put this information in the log, at a level higher than DEBUG, as the last log item before sleeping.
