Erick: In my case, when server hangs, no exception is thrown, the logs on both servers stop registering the update INFO messages. if a shutdown one node, immediately the log of the alive node register some update INFO messages that appears was stuck at some place on the update operation.
Other thing that I notice is the fact that the cluster hangs more frequently when the collection has replication. -- Yago Riveiro Sent with Sparrow (http://www.sparrowmailapp.com/?sig) On Sunday, June 2, 2013 at 2:28 PM, Erick Erickson wrote: > Yago: > > Batches of 100k docs at a time are pretty big, you're way past the > diminishing returns point.
