PROBLEM is gone/solved -- PERHAPS there were no objects available for the first ~30min ... seem ok now. Tried to abort or_req 93185 ... as that was in the queue, but only for execution after midnight. Other time critical ORs are inserted for after 22:00 UT, perhaps that is affecting something ? Comment fom Mads: The conductor had crashed eariler that day. |
