@michaeldrogalis thx for your reply and sorry for my late response. I'll try to track down whether the peers are valid with regard to the scheduler being used (balanced). However, I'm still curious why using tags is a problem when everything runs fine without them. Will let you know about the solution.
@atwrdik Because tags constraint what peers are candidates to run what jobs.
@michaeldrogalis Totally aware of that. But even after starting a ridiculous amount of virtual peers (which definitely should have been enough) the problem still exists.
@atwrdik Okay. Can you come up with a minimal reproducer? It could definitely be a bug. That would be helpful for me to diagnose.
@michaeldrogalis need to finish another task first. Will let you know as soon as the reproducer is ready.
@atwrdik Cool, thanks!
