I also get sio overflows all the time... sio1: 1 more silo overflow (total 1) sio1: 1 more silo overflow (total 2) pid 337 (ppp), uid 0: exited on signal 10 pid 642 (ppp), uid 0: exited on signal 11 pid 660 (ppp), uid 0: exited on signal 10 sio1: 1 more silo overflow (total 3) sio1: 1 more silo overflow (total 4) I compiled ppp with the debugging symbols in, and took the setuid bit off it. Below is what happened when it crashed...gdb seems to be unhappy. BTW, I'm running a SMP system as well.
