Thanks, that could be it.
One test I'm running is pinging (I ported the ppp_test.c test app in the no-longer-tested archive into a class for our app) various hosts and internet sites to make sure routing works properly over the PPP link and there are a lot of receive timeouts and I'm sure some of them take long enough to time out that PPP is brought down in the tail end of them.

Lots of swearing and fixing cryptic auth.c compile errors.
I posted about it on the list in late August:

Looks like someone broke the code base a little after 2004....

Hi Ken,

OK. This must be a memory leak somewhere.

However I fixed a fiew memory leaks with my enhancement patch for the FreeB=
SD
See Bug# 1001656. Maybe you try to use this first.

One major flaw was, when you do a IF_DOWN the unsent buffers must be cleane=
d up too.

By the way, how did you compile your target with PPP in the first place?
This does somehow not compile, as far as I know.
