@battermann Do you remember any details regarding these log messages?

The federator CPU issue might be related to the event of what is being logged. There seemed to be two log messages per error: one of it was a multiline json message reporting a HTTP 500; the second was a more haskelly one line saying KilledByHttp2ThreadManager (Just ConnectionIsClosed).
