FreeBSD 4.8-R user ppp P II - 400 128 MB RAM 56K ext. modem, 45.3K connection When I updated from 4.3-R to 4.8-R recently I immediately noticed a strange hitch in the flow of received data from user ppp to TCP/IP applications. For example, with the BSD ftp client, when receiving a file, the progress always stops around 113 KB and ftp reports "stalled" for about 10 seconds. Then the ftp client suddenly shows 170 KB received and for the rest of the transfer there are no more hitches. This is 100% repeatable. During the 10 seconds when ftp's progress is "stalled" at 113 KB the RxD LED on my external modem shows continuous data flow. Both Netscape and Opera show the same hitch under 4.8-R. I tried transferring a large (40 MB) file across my 10 Mb/s LAN several times with the ftp client and never saw any pauses. 4.3-R definitely did not do this. Anybody got any ideas? I've already tried the 4.3-R ppp binary on 4.8-R: same behavior.
