    Hi!

    We have a problem with our pptp-Server running under Linux.

    Dist: SuSE Linux 7.2 (i386) / Kernel 2.4.18-18mppe
    PPTP: PoPToP v1.1.4-b4
    PPPD: pppd version 2.4.1 with MPPE-Patch

    The topologie is the following:

    PPTP-Server ** Firewall ** Lotus Domino Server 6.x

    The Problem:

    If someone connect to the pptp-Server and work (NetOP, VNC,
    Citrix a.s.o) all works very fine and fast. But if he use the
    Webinterface
    from the Lotus Domino Server after reading long emails we get a
    kernel freeze (nothing work anymore). The Logfile say's nothing:

    [Here the kernel freeze]
    -CUT HERE

    I'm searching the internet for a while but can't find any solution
    for
    such kind of problems (or how to find out what happens...).

    Thanks!

    Best regards,
    Kai.
