I think that instead of trying to guess a value that would be correct for many filesystems, but obviously wrong for others, we should just remove the explicit size. > - for EMFILE - is the limit on open files really 64 per process? Not necessarily. It's what kern.maxfilesperproc says. On my CURRENT system that is a little lower than kern.maxfiles: # gothmog:/home/giorgos$ sysctl -a | grep files # kern.maxfiles: 8072 # kern.maxfilesperproc: 7264 > (And of course, tuning(7) also has some historical figures) Can you help us identify them? - Giorgos
