Description Yuri Victorovich freebsd_committer 2017-04-06 16:27:15 UTC
scanimage from sane-backends-1.0.25 can't be killed (-9):

>   PID  PPID  PGID   SID  TSID THR LOGIN    WCHAN     EMUL          COMM        
> 34808 34807 34807 25735 25735   1 yuri     cgticb    FreeBSD ELF64 scanimage   

I think it's almost always a bug in kernel when some system call never exits like this.

The original command was:
> scanimage --resolution 600
