Rodney, many thanks for your engagement in this matter. It seems that you were
right suspecting that arc_max is the culprit. After reducing its size virtual
machines are working stable for over a day. So, instead of stability issue this
was more like user experience issue. As you see we both were tricked by top(1)
output which looked fine and didn't indicate problem. Is it possible to have a
notice printed in dmesg that happens (as we have for other kernel limits)?
