Hi
I have a fairly new installation at a client running in Multi-POD. They are running version 4.1 but since we started to configure and migrate servers we get exceptionally slow responses from APIC.
In many cases we receive response errors on both SSH and WEB interfaces if I try to interrogate the leaf nodes - "ErroApplication Centric Infrastructure: Unable to deliver the message, Resolve timeout from (type/num/svc/shard) = switch:104:4:0, switch:203:4:0". in general the response time to INB and OOB networks is around 60ms on the VPN link (I am not on site), although we get the same issue there. In many cases, it seems configs are not pushed to the nodes once applied.
Similar issues are experienced depending on where you navigate on the UI.
