Description
This is from Hudson build 1738, if a log is about to be rolled and the ZK connection is already closed then the replication code will fail at adding the new log in ZK but the log will still be rolled and it's possible that some edits will make it in.
From the log:

The easiest thing to do would be let the exception out and cancel the log roll.
