I think more info is needed. What kernel and btrfs-progs versions have been tried? What hardware? What is btrfs fi show and fi df <mp>? What files, are there snapshots, etc? Is there any pattern to the two cases, like the same types of files? And what are the kernel messages for the above scrub (the entire scrub)?
When you say don't have any hardware issues, I'd like to think that means an exhaustive (tedious) look at all kernel messages since the last good scrub to see if there have been any libata or mount errors, and smartctl -x shows no problems, and at some point in the life of this machine's current configuration an exhaustive multiple day memory test? Otherwise I don't know what no hardware issues means. The csum errors not being fixed sounds like it's probably single copy data corruption, is that correct? And are the files actually corrupt? Can you extract them with btrfs restore and are they actually broken (if this is even practically determinable)?
