Brian: If he's having the same lockup as me, PPP is blocking on a select() while trying to re-establish a connection that has gone down. If there's a pppctl socket open and you're issuing commands it doesn't lock up. But when you shut down the socket by terminating pppctl the lockup occurs. The lockup also occurs if pppctl wasn't running at the outset. To reproduce the problem (and it's easily reproducible here), pull the client's Ethernet cable. The client will retry properly once. The second time it retries, it will lock. Since this may be adapter-dependent, try with an ed card (I think that everyone in the universe must have at least one of these). --Brett At 06:32 AM 5/21/2001, Brian Somers wrote: >Hi, > >I think it's important to quantify what a lockup is here. > >If pppctl is still working (ppp will talk to it), then it may be >worth seeing what ``show physical'' and ``show timer'' say (is the >link open, or is ppp waiting for something to happen via a timeout?). > >If pppctl isn't working it's worth building with -g and trying a kill >-11 (or attaching with gdb) to get a stack trace. > >Brett Glass (cc'd) has complained about a similar problem where it >seems that the ng_pppoe node is locked up.
