PI Buffering running out of capacity - History Recovery

Hi Team,


We are doing a back-filling activity where we have a PI HDA Interface reading from our SCADA source systems for ~10 years worth of data.


We are trying to hit the 'sweet spot' on the number of tags and the duration we should recover in one go. We are finding that once we start the recovery with the settings below (which are pretty tame, would expect PI to handle without any fuss) the buffering capacity starts running out of space really quickly. The events in queue are around the 40000 events mark (this could be an issue?). Is there a setting we might have missed that is throwing the Buffering queue haywire?
