NSX - Some controller connections down from ESXi hosts

[dvino821]

Running NSX 6.1.1. Having connectivity issues between VMs on some VNIs. Some controller connections from ESXi hosts show down (see example below).

Restarting the netcpad doesn't seem to help. Any feedback would be appreciated.

UPDATE: We bounced the controllers and that fixed the issue, but need to find out why this keeps happening.

Thanks,

Dave

I recommend to upgrade to 6.1.4 as there were controller issues fixed (like this) between 6.1.1 and 6.1.4

Thanks! I thought that might be the advise. Unfortunately, we are allowed to upgrade at the moment.

Do you happen to know if this exact issue was fixed?

Thanks,

Dave
