The load itself wasn't that high, it was actually much higher yesterday.
The CPU graph shows a high value for "user" and "nice", that's untypical comparing to the historical data.

We have never disabled the alert and the problem did not reappear so is not reproducible. By now we likely do not even have logs or data to check further so just assuming this is gone for good.
