Hi Ludse,

this issue was completely lost in space, sorry about that.

I forgot to mention that this is a host event handler.

Unfortunately, is_volatile seems to be a service only option, and I am
checking the host. When I define a service to that host which has the
is_volatile option set, the service event handler is never called
since the service is not checked again once the host is in DOWN state.

Any additional hints?

Greetings
Marc
