I see this:
newssvr15:root> tail -70000 /var/log/debug | wc
70000 1255826 12390095
newssvr15:root> uname -a; uptime
Linux newssvr15.news.prodigy.com 2.4.5-ac5 #4 SMP Wed Jun 6 12:37:23 EDT 2001 i686
unknown

And on the oldest systems I could find easily:
gatekeeper:davidsen> tail -70000 mail/inn-workers | wc
70000 388964 3279144
gatekeeper:davidsen> uptime; uname -a

newsutil1:davidsen> tail -75000 /home/davidsen/nsmail/Trash | wc
75000 112995 4554404

I can't seem to find this behaviour on any Slackware, SuSE or Redhat
system even on systems last modified in 1968. This looks as if it works
fine. You're not running obsolete software are you? Or your own custom
version of 'tail'?
