This is my first time posting for this community corner and i just hope i didn't violate any rules for the first time poster. :D
I am using Nexus 1000v in our Cloud Service, we have 4 Blade ESXi clustered host and 2 Nexus 7000 directly connected from HP C7000 Enclosure. We've been using this setup for almost a year now then one day we started experiencing disconnection of some VMs. At first, the solution we made is to reboot the VM. But i found out that instead of rebooting the VM, i just do a 4 packets ping to its gateway. 2 packets were failed and then the succeeding packets are already successful. The issue has been repeatedly happening so what i did next is to leave a continuous ping from VM to its gateway. That permanently resolve the disconnection issue. When i came across the logs of N1Kv, i noticed the logs below pertaining to the disconnection of the VM;

Any one who also experience this? And/or anyone has an idea why was this happening?
