I've noticed this morning that my CouchDB (0.9.0) server is re-indexing all 19000 records in a database for a design doc:

View Group Indexerevents _design/Event<0.19507.9>Processed 10186 of 19210 changes (53%)

Any ideas on why this might be happening? It's happening over and over again, killing my site. It was happily indexing incrementally until this morning, too, which confuses me.
