> MongoVersionGCSupport uses the default batchSize when it queries for possibly deleted
documents. The default will initially read 100 documents and then as many as fit into a 4MB
response. Depending on the document size a couple of thousand will fit in there and take time
to process. It may happen that the MongoDB cursor then times out and the VersionGC fails.
> An easy and safe solution is to reduce the batch size to a given number of documents.
