Hello James,

In which configuration file and environment variable are you setting
-Djute.maxbuffer
? ZooKeeper can pass in many places the JVM flags that could be used to
define to pass jut.maxbuffer. Ideally zookeeper-env.sh under the ZooKeeper
configuration directory should be the right place where you export flags
such as JVMFLAGS,  SERVER_JVMFLAGS or CLIENT_JVMFLAGS.

regards,
esteban.
