Justed patched our lab smartzone which is running 6.0.0.0.1331.

After "service restart"  I only get to see "Wait for (Cassandra,Communicator,Configurer,Core,Courier,ElasticSearch,Mosquitto,NginX,RabbitMQ,ScgUniversalExporter,Switchm,Web) up.". After couple of hours I rebooted the smartzone. 

I now shows a date/time at "Applied On" column at the script page

@ludia_it i did exact same thing but as I had only one dev vsz on 6.0.0.0.1331. I thought it was a bug from my dev environment. Was late just a few minutes before midnight yesterday.

@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.
