I didn't see any mention of the btrfs utility version in this thread (I may be blind though). My server was suffering from frequent panics upon scrub / defrag / balance, until I updated the btrfs utility. That resolved all my issues. My server has two BTRFS filesystems of ~25 TiB each, and 4 GB of RAM (15% used). A hardware upgrade is imminent; just waiting for the backup to complete. ~~ Andrew E. Mileski
