Hi. After an upgrade from 9-STABLE I have a problem with mpd5. It can go to an endless loop while accepting a new pptp connection with a probability of like 50%. It looks in its log like I show below. The loop starts and ends with "LCP: LayerUp". This is really an endless loop, because neither mpd5 nor windows 7, which I use as a client cannot break it, it can last for minutes (the output below was interrupted when I pressed 'Cancel' button on the client). I don't see any packet drops or other network problems. Furthermore, this machine was running fine when on 9.x. problem appeared after 10.x upgrade. This has nothing to do with a pf, which I use to filter the traffic - the problem persists when I switch it off. I've also rebuilt the mpd on 10.x, and this didn't help. ===Cut=== Mar 17 14:44:22 taiga mpd: [L-2] Accepting PPTP connection Mar 17 14:44:22 taiga mpd: [L-2] Link: OPEN event Mar 17 14:44:22 taiga
