We are using Veeam Backup to backup our ESXi 3.5 and we had problem once in a month with the below error.
Analyzing object "XXXDC5" (64), host "penvmware4
" Failed to login to "xxxvmware4
" by SOAP, port 443, user "root", proxy srv: port:0 Log
in failed due to a bad username or password. T
here are no objects to backup
All VM serves are still online running and user able to work on it. We tried to restart the VM network and agent, however it also failed.
We always need to reboot the host itself.
However this does not happen in our ESX 3.0 and 3.5 server.
