I have those as well, on NetVision cable:

Jul 18 06:04:38 furr pptp[12499]: anon log[decaps_gre:pptp_gre.c:397]:
buffering out-of-order packet 1091406 (expecting 1091405)
Jul 18 06:04:38 furr pptp[12499]: anon log[decaps_gre:pptp_gre.c:391]:
discarding duplicate or old packet 1091405 (expecting 1091407)

My guess: PPTP implements GRE itself (instead of using a network stack
provided by the kernel), and instead of reseting the connection over
an error (is there any way to request a re-send on GRE?), it swallows
the error.

No harm done, I guess. Those kind of errors probably happen daily on
your TCP connections but you don't notice them since TCP silently
recovers.
