I piped more than 8 tb of zeros through pfinet over the last two hours with no ill-effects on the system (other than the page fault and page zeroed counter overflowing somewhere).

I'll close this bug now, feel free to reopen if you can still reproduce it.

17:28 <antrik>: fifo does crash as well, though not as fast
17:29 <antrik>: and Neal's patch doesn't change the situation

02:31 <antrik> interesting: running "cat /dev/zero|cat >/dev/null" for a while completely freezes the system
19:54 <antrik> hm... cat /dev/zero|cat >/dev/null crashes the machine also if done in a chroot...
How long does this take?
20:20 <antrik> tschwinge: not sure exactly. must be something between 15 minutes and an hour I'd say
11:49 <antrik> if instead of doing "cat /dev/zero|cat >/dev/null" (pflocal) I use tcplisten/tcpconnect (pfinet) or a fifo, there is no crash
13:41 <antrik> a simple "cat /dev/zero >/dev/null" doesn't crash either
13:44 <antrik> so, any volunteers to find out why pflocal crashes Mach? :-)
13:44 <antrik> (or at least it crashes the whole system even if run in a subhurd...)

Perhaps related to the pflocal patch by Neal that is in the Debian package?
