cron/senddigests runs every day at noon and is responsible for the
exception that happens at noon or just thereafter.

There are no retries per se. The list has a setting
digest_size_threshhold (on its Digest options page). When a post
arrives that makes the digest.mbox bigger than digest_size_threshhold,
a digest is triggered immediately. In this case, the digest.mbox is
bigger than digest_size_threshhold and the digest is never
successfully produced so every post to the list tries to send a digest
and causes the exception to be triggered again. Thus, all the other
logged exceptions are the result of a post to the list triggering the
digest process.

If there were no posts to the list, the process would only run once a
day.
