Yes we seem to be experiencing different behavior. We had an update to a snapshot that was over 1000 items. We received the first 1000 items and then received that we lost raw updates on the remainder of the updates. When we changed the value for max_buffer_size in the conf file, we received all updates.

Some more information that may be helpful is that this behavior was on a demo license. We have not tried a similar situation on our production instance.
