During an OSS outage, we had a client crash with the following log:

This looks like a duplicate of ~~LU-6716~~, but that was marked as a duplicate of ~~LU-3259~~. That ticket had two patches land to master, but only one landed to b2_7_fe. Assuming that's actually the fix for this issue, can we get patch 10859 backported to b2_7_fe?
