Zookeeper CLI Error - IOException <len12343123123> Out of Range

Question

Running zookeeper 3.3.3. I have a znode that I'm just trying to list through the CLI, as in:

ls / myznode / subznode

This fails with an IOException in org.apache.ClientCnxn $ SendThread.readLength on line 710.

Has anyone seen this? Someone suggested that possibly bad data is in znode. Not sure what, or how ... but I can’t delete it, because there is something in it.
