The process which writes data consumes 100% of CPU in system state: {agata}/home/mitya% ps -p 58796 -o systime,usertime SYSTIME USERTIME 0:59.56 0:00.08 58796 mitya 1 103 0 27808K 4820K CPU11 11 0:53 100.00% bsdtar As soon as I free some space, the problem disappears until space fills up again. Since I have the recommended 8% of reserved free space, I expect writes to work well until all free space is exhausted. -- You are receiving this mail because: You are the assignee for the bug.
