PPTP 100% CPU Usage after disconnect


If i establish a connection with pptp and close this connection i get
100% CPU usage and in the log file i get thousand times : Failed to
open /dev/pts/22: No such file or directory as below:

I'm using kernel version 2.6.15.3 and udev.

My assumption is that udev deletes the device before pppd has finished.

How can get round this ?
