Sijie Guo updated BOOKKEEPER-667:
---------------------------------

    Comment: was deleted

(was: this issue would be easy to remove the conditional check when 
errorOutOutstandingEntries. since channelDisconnect would be triggered in 
either case: 1) client manually close channel; 2) netty close it due to channel 
is broken. we can't guarantee when #channelDisconnect would be triggered. so 
the safe way is to error out when received #channelDisconnect like what we did 
here:
