fio team, I've found a bug that results in fio hanging at the end of a workload involving log generation, in this case specific to latency log generation. The bug appears in version 2.1.14, 2.2.4, and possibly others. I have tested these scripts with 2.0.9 and they work. Slightly different scripts work on 2.0.14 as well. Error message and script file are copy-pasted below. The job that times out is not always the same job but, usually at least one does time out, it's worse with more targets. fio: pid=37182, got signal=11 fio: job '/dev/sdc' hasn't exited in 60 seconds, it appears to be stuck. Doing forceful exit of this job.
