Steps to Reproduce:
enable and provision eventbus role and watch affected log files.

Actual Results:
The following logs are continually written to until the virtual hd is full.
/var/log/messages
/var/log/syslog

It looks like this is due to kafka-server and changeprop services being stuck in retry loops.

Sample log output:

Expected Results:
Services to not fail and get stuck in retry loop
