When being restarted, the Agent shortly connects to the CMR but then disconnects again and is not active.
In the Agent logs, a ClassNotFoundException wrapped by a KryoException (error during deserialization) occurs.
In the CMR logs, a KryoException (error during deserialization) occurs, too, wrapping a KryoException (Buffer underflow).
There is only few memory left (~3%) on the CMR machine.
On another subsequent restart, the Agent connects correctly.
