[Gee whiz, I went off and did non-developer stuff for a few years
and they changed everything on me! ;-) ]
I'm trying to debug why pppoe (usr.sbin version) dies under load
for me. Summary: I am launching it from ppp using an appropriate
set device "!/usr/sbin/pppoe -i fxp0"
line, and it works for light network activity, but if I copy a 100K
file in either direction, pppoe exits causing ppp to recycle the
Anyway, when I connect to the running pppoe process with gdb and
break on _exit, all I ever get for a stack trace is
Argh! I wanna see where it came from! I tried linking the whole
thing -static: no help. I now see that there appears to be two
libc's: ordinary libc and "reentrant" libc_r where presumably
everything is thread-safe.
