I can see some of carbonio CE services are not running. Is there any particular reason for that? 

carbonio-files.service                             loaded activating auto-restart       Carbonio Files daemon
carbonio-message-broker-sidecar.service            loaded activating auto-restart       Carbonio message broker sidecar proxy             
carbonio-message-broker.service                    loaded activating start        start Carbonio message broker daemon                 
carbonio-tasks.service                             loaded activating auto-restart       Carbonio Tasks daemon
carbonio-ws-collaboration.service                  loaded activating auto-restart       Carbonio Workstream Collaboration daemon

also, we can not check the service health status as per:

root@xxxxx:/home/xxxxx# curl -s -v   http://127.78.0.4:10000/health   | jq
*   Trying 127.78.0.4:10000...
* TCP_NODELAY set
* connect to 127.78.0.4 port 10000 failed: Connection refused
* Failed to connect to 127.78.0.4 port 10000: Connection refused
* Closing connection 0
root@xxxxxx:/home/xxxxx# 

Just restart the server and then do;

su - zextras -c 'zmcontrol restart'
systemctl restart carbonio-tasks
systemctl restart carbonio-message-broker
systemctl restart carbonio-message-dispatcher
systemctl restart carbonio-ws-collaboration
systemctl restart carbonio-videoserver

Now, check all the status using following commands:

su - zextras -c "zmcontrol status"
consul members
systemctl list-units carbonio*
curl -s -v http://127.78.0.4:10000/health | jq

And if you still find any service not running, try finding some clue using:

journalctl -u <service-name>

For Example: 
journalctl -u carbonio-tasks

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.
JOB    = Pending job for the unit.

44 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.

And the second answer...
