I have the same issue: kcompactd0 regularity (about every 10 days)
blocks (iowait?) and never recovers. After a few more hours, the system
becomes more or less dead.
I never had this issue until, I would say, 2 month ago. I was running
Ubuntu 18.04 fine until then. No heavy load on the server.

btrfs-transaction seems OK though:
