Hi all,

Hi Jean-Claude
It seems like your control system does not have any Starter defined.
Is it right ?
If it is your case, create a Starter device with Jive and restart Astor.

I confess, it is a bug, the code does not check if the control has Starter device.
The Tango installation create by default a Starter device.

Pascal

Hi Pascal,

thanks for your answer, but i think a Starter is well defined and service running.

FYI, there is no problem from another host (Tango 7.2.6) with older astor (5.4.1) !!!

Thanks,

Hi,

the problem was due to the Starter instance name that contained dots (.)

deleted it
recreated a new instance of the Starter, without dots
restarted the Starter

Well running now :slight_smile:

Thanks
