ACi APIC Error: the messaging layer was unable to deliver the stimulus

[hashimwajid1]

hi 

we have APIC cluster UP and running since many months. recently we broke the APIC cluster in order to relocate the APIC on different Racks. after relocatin we are getting bellow error frequently

                        the messaging layer was unable to deliver the stimulus

now we cannot register any new leaf in existing fabric and other 2 APICs shoiwng not available on APIC1

APICs are not synchronizing with each other even we restarted all APICs but no luck

APIC version is 3.2

If you login to APIC2 and APIC3, how do you see the status of the cluster?

Can you share the following logs, from each APIC individually:

bash
controller

Are you able to ping between then using the infra IPs? You will see the IP addresses in previous cmd, but must likely are 10.0.0.1, 10.0.0.2, 10.0.0.3.

Cheers,

Sergiu

Hi,

issue solved, APIC cables were wrongly connected. we modified the cables and APIC cluster formed.
