It means you're getting garbled packets from the peer.

If it's persistent and doesn't correct itself over time, the most
plausible reason (I think) would be that you're using MPPE (MS
proprietary packet encryption) and there's a bug in that code.

If it just happens intermittently and then fixes itself, I'd ignore
it.  The cause would be dropped or corrupted packets and recovery by
the encryption code.

It appeared to be happening every couple minutes and causing
the VPN to go down (even though pppd was still running) so I had
to kill pppd and let it restart. That fixed it till the next time.
So probably like you say it is mppe.

Thanks
