<p dir="auto">More details:</p>
<ul dir="auto">
<li>Coord+overlord node is still at 0.12.1 (we havent upgraded it yet, for fear of more damage)</li>
<li>another replica of MM node (we deploy 2) has been running without issue. we are very, very scared that if that replica dies and gets stuck like this, ALL ingestion will stop!</li>
</ul>
<p dir="auto">All help is highly appreciated.</p>
