[ovirt-users] Mantenance mode error

[nicola.gentile.to]

Hi,

I have a problem. I try to put in maintenance mode the host, but the 
message that is displayed is this

"Error while executing action: Cannot switch Host to Maintenance mode. 
Host has asynchronous running tasks, wait for operation to complete and 
retry."

I checked the log file engine.log:

"2016-10-10 14:32:53,841 INFO

How can I revolve?
