@ludia_it 

I can confirm this all other nodes I tested with 5.2 worked fine. We have some vSZ-E, vSZ-H and SZ104, but only one at 6.0.0.0.1331.

@vineet_nejawala @allan_grohe 

There should be a workaround added for 6.0.0.0.1331 that if you see this message repeating more then 5-10 minutes. Login in a new session and reload the node.

"Wait for (Cassandra,Communicator,Configurer,Core,Courier,ElasticSearch,Mosquitto,NginX,RabbitMQ,ScgUniversalExporter,Switchm,Web) up."

Else they will never come back.

@ludia_it @nick_nordberg thanks for sharing your experience with 6.0.0.0.1331!

I have 3 vSZ clusters.
On the first node the services came up after few minutes as expected.

Here is the session output:

The other node were stuck after restarting the services.

Eventually  I restarted it via another SSH session.

@roy_beiser This is exactly what I experienced when I upgraded my single dev node. It will be stuck there. Just do a reload in a separate cli window and it will work after restart

fine again.
