I saw lots of these (30-40 per minute under load) on my link to home (2x 56Kbps ISDN DOSBS), from a BitSURFR Pro to a Livingston PM3. Thinking it was serial-related, I played with MTUs and the like for some time without any improvement. Finally, I disabled VJ header compression, and the messages ceased *entirely*. I haven't looked any further. (My Linux box has been running current 2.1.x kernels, for whatever that might be worth.)
I *might* recall reading about VJ-related issues between Linux and PortMasters, maybe a year ago (time ~ -infinity!), but haven't been able to find anything in a few minutes of searching, so maybe I'm dreaming it.
There may not be *modems* involved, but what about PPP links?
