It happens when allocating requests to more than 16 different L2 tables are queued because they depend on other requests. It causes a qemu abort(), but image consistency is not harmed. Critical enough to be fixed in 6.3, I'd say. I found a reproducer, added it to qemu-iotests and sent upstream patches. RHEL code is different, so I'm working on a different fix there.
