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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
