I keep experiencing system crashes that look like (I think) are caused by
the pptpctrl process.  I really need help on this one as it is causing big
problems.

The system:  i386 RedHat-7.0 with all current updates applied.  PoPToP-1.1.2
and pppd-2.3.11 with patches for mschap-v2, mppe, require-mppe and strip
msdomain added.

The log:
