OK, I guess there's something about your setup that makes it difficult to
assign static host_id's.

Perfect, that shows exactly where the bug is. There's a case where it has
missed saving the latest dblock values, so random values are being copied

to test it.

Not very unusual when you have lock contention (multiple hosts trying to
acquire the same lock concurrently.)
