We've been looking at this off and on in bug 1696317, without any firm leads as of yet.
Lemme add Jan-Erik here so between us all we can figure out what the next steps are. This isn't as rare a crash as it appeared in that bug, so maybe we go through and start annotating IO Errors?

Oh, and let's bring :kinetik to the party, too.

Without a reproduction, I think we need to go through our code base, find the places where we unwrap any potential IO errors and either figuring out if we can handle it more gracefully or at the very least at more comprehensive panic messages might get us a step closer in finding out what's going on.

No errors since v89.0.2, so I'm cautiously gonna close this out.
