I've never seen this happen. Looks like you might be using 9.1? Are you up to date on all the 9.1.x releases? Do you have just 1 slave syncing from the master? Which OS are you using? Did you verify that there aren't any network problems between the slave & master? Or hardware problems (like the NIC dying, or dropping packets)?
