Cause

SSH keys were generated for some user accounts and installed on the appliance.

One of the trusted ssh keys was created with the "id_rsa" key instead of the "id_rsa.pub" key.

This caused the ssh key to exceed the maximum size of 256K supported by the appliance.

Solution

Remove any user defined ssh or public keys listed in the error logs and recreate the ssh key with the id_rsa.pub key.

Install the new key on the appliance.
