We have a load of dataflows that all use the same template and ran well over many years. All of a sudden I am getting problems with the History_Preserving transform. A dataflow that did run ok now suddenly dies with this message (notice the odd ‘d’ in the message):
Transform History_Preserving d not run. Job Server not responding.
It only happens in two dataflows. All the rest still works. I replaced the History_Preserving transform by a new one and even rebuilt one failing dataflow from scratch. Also ran it on two different job servers.
We’re running version 18.104.22.16802.
Anybody seen this before? What’s going on?
