In my case I was lucky and saw event 10014 from MSExchangeIS Mailbox Store saying "Available disk space for the database logs is extremely low. Message delivery to the database may be stopped.".

I traced the cause back 4 days to event 4121 from MSExchangeRepl saying "The Microsoft Exchange Replication service encountered an error when retrieving the database copy statuses during the periodic operation 'AmPeriodicDatabaseStateAnalyzer'. The operation will be retried later." When replication fails the transaction logs are blocked from flushing after full backup. This caused a buildup of 90GB worth of transaction logs which needed to be deleted.
