I have two machines running 2.0R, dogs and holiday. I've applied the patch to if_ppp.c, otherwise it is "out of the box". Here's the problem: I connect them using ppp, the connection is initiated from dogs. Everything looks fine. I ping holiday from dogs. This will run from 5 - 20 minutes then holiday becomes unresponsive. It doesn't drop the connection, it just hangs. Logging into holiday (via a different route) I find that the pppd is running, it has logged many FCS errors and a few queue full errors. If I run top, pppd is consuming somewhere between 85% - 112% (!!) of the cpu, apparently in a pretty tight loop. Only -KILL will stop it. This behaviour occurs each time I connect. I haven't tried connecting/pinging the other direction. I've recompiled pppd with debugging enabled so maybe I can find out what it's doing. Any ideas as to what's happening? Any thoughts will be apprecitated. Some specifics: Dogs is a vanilla system, 486/33Mhz, 16M, IDE drives, standalone. Holiday is 486/66MZ, 32M, EISA bus, with Ultrastore 24f controller, 32bit EtherLink III ethernet adapter. The ppp connection is via a pair of Intel 14.4 modems running at 9600bps with compression and error detection. Thanks, Dayton Clark CIS Dept.
