After taking a closer look, it appears the problem is that the fio process is stalling in userspace. Looking at the ps listing, the fio process hasn't run in over six hours, and using attaching strace to the fio process, it's stalled in a FUTUEX_WAIT. Has anyone else seen this? I'm using fio 2.2.6, and I have a feeling that I started seeing this when I started using a newer version of fio. So I'm going to try roll back to an older version of fio and see if that causes the problem to go away. - Ted
