Got a client reporting a kernel panic with pptpd.. not sure what could be
causing it. Decoded Oops also included. Anyone have any ideas as to what
could cause it?
Single-processor X86 box; kernel 2.4.17; vanilla except patches for mppe
in ppp module. Apparently, this error is caused when users log in and out
of the VPN in quick succession. It's happened twice today.
Please let me know if you guys need more info. Thanks!
