We have a node that has 200K items and would like to delete them. getChildren() keeps failing. Is there anything that can be done?

Hi Jordan,

We had the same problem a few months ago.
Are you getting an IOException("Unreasonable length = " + len) on client
side?
You have to set the system property "jute.maxbuffer" to a value >= <length>
on ZooKeeper client side.
