3.2.6.2 Maintenance Timer Expiry

When the Maintenance Timer expires, the DRT node MUST attempt to detect cloud splits (as specified in section 3.2.6.2.1).

If a node finds that it has no entries in its cache, it SHOULD also try to resynchronize with the nodes it knows to obtain more entries. Synchronization is initiated when the node sends a SOLICIT message, as specified in section 3.1.4.3.

The DRT node MAY<5> also resolve any keys to ensure that the cache requirements continue to be met, as specified in section 3.2.1.1. If it does so, then the ResolveReasonCode MUST be set to REASON_CACHE_MAINTENANCE.
