Hi,
I'm experiencing a strange behavior of one of my ESXi (7 total in my cluster) every single night.
I don't have this problem during the day but (coincidence ?) when my Veeam backups start and after a couple of hours, one of the ESXi doesn't respond to ping anymore.
So I get the "could not reach isolation address" error...next "Host is not responding"...and finally after a few minutes, everything comes back to normal...
To me, it almost looks like if the server can't handle the multiple snapshots that the backup software generates on it and finally stops responding...
vSphere 4.1.0 has been reinstalled on the server.
The mother board and all the network adpaters have been replaced.
Nothing changes.
Any idea what the root cause might be ?
Thanks !
Eric
