The article describes possible reason why CS would timeout when adding an RMA device back to cluster. 

Cold sync between two nodes takes more time and getting timed out.
After few minutes Secondary node goes to disable state.
Even after reboot the Secondary node its the same behavior again.
Secondary node gives the below error for show commands. error: the jsrp-service subsystem is not responding to management requests 

If customer has speed configured on interfaces s mentioned below we may see the issue :

set interfaces xe-0/0/0 gigether-options speed 1g
set interfaces xe-7/0/0 gigether-options speed 1g

If this config is really needed then we have to configure  no-auto-negotiation on those interfaces.

Error:

root@TEST# set interfaces xe-0/0/0 gigether-options speed 1g 

{primary:node0}[edit]
root@TEST# set interfaces xe-7/0/0 gigether-options speed 1g

root@TEST# commit check 
[edit interfaces xe-0/0/0 gigether-options speed]
 'speed 1g'
  Enabling gigether-options auto-negotiation is highly recommended to prevent traffic drops due to RF peer link up. But if needed, no-auto-negotiation can be enabled
[edit interfaces xe-7/0/0 gigether-options speed]
 'speed 1g'
  Enabling gigether-options auto-negotiation is highly recommended to prevent traffic drops due to RF peer link up. But if needed, no-auto-negotiation can be enabled
error: configuration check-out failed: (statements constraint check failed)

Since there is configuration commit issue, the CS would fail.

In the above example, we have to configure no-auto-negotiation on interface where speed is configured.
