Hi Shane,

Thanks much for the hints you sent me. Since I'm pretty swamped with

"variable 'kern.eventtimer.choice' not found"

With "kern.eventtimer.periodic=0" - same result.

What other values would be valid for "kern.eventtimer.timer"?

Yes, absolutely the same.

Haven't tried this, since I need to go to 9.1 on this system
anyway. Besides that the server is in a remote DC so changing disks is
not an easy thing to do.
