   The root cause is [this PR ](https://github.com/apache/bookkeeper/pull/3383).
   
   The problem is that we cannot call [await() ](https://github.com/apache/bookkeeper/blob/be7053b850a3ad53c09baeac15b01cabc8e9412a/bookkeeper-server/src/main/java/org/apache/bookkeeper/proto/PacketProcessorBase.java#L139)from an IO thread, even if we don’t have the consolidation in place
   if the socket buffer is full, that blocking call would cause a deadlock, also without the consolidate
   the await() was added, under the assumption that all these calls were coming from a thread pool dedicated to read operations.
   
   I will push a fix to bookkeeper side and create a new release for fixing this.
