[MiNT] Possible pppd based my-system crashes
I get quite a few crash and reboot errors when doing anything
other than reading mail or newsgroups. That is when I am typing
e-mail or a reply to e-mail over a ppp link.
These show up as aessys errors, segmentation errors, bash errors,
toswin2 errors, and sld errors.
Most of the error reports have something to do with a tcp_send
seg outside win. I do not know what is complaining about who,
in this context, or whether an outgoing error or incoming error
is involved. Pppd somewhere is complaining about something.
Most of them happen when I am typing fast, my normal speed, but I
tried typing slowly, and that did not help either. Anything
coming from my keyboard, TT030, TTM 195, MiNT 1.15.12, will
eventually, and quite quickly, cause a system crash, working
on e-mail, in pico and pine, over a ppp link.
There are three areas of commonality possible. The first is MiNT's
keyboard buffer, on the assumption it has one, being either too
small or too slow, or too fast. The second is whatever buffer pppd
sets up, and how it interacts with the keyboard buffer. The third
is netBSD's pppd.
If anyone is looking through the MiNT source code for either of those,
and finds a buffer being set up, it would be a boon if they would
make it a little bigger, and my mean-time-to-failure on typing
something on a remote host might go up a little.
If anyone could suggest another place where this problem might be
hiding, that too would be appreciated. At this point, I do not
know where to look.
A further complication is that I have no crashes, repeat,
no crashes, when replying to a UseNet newsgroup posting. It might
even be at the other end.
However, what I use for a newsreader is different than they provide.
I have tin aliased to tinx. This is also somewhat of a new problem,
and my remote host has upgraded versions of netBSD recently.
Somebody somewhere has a buffer overrun problem, I think. If anyone
anywhere could suggest where it might be, I would be greatful.
This is being typed off line, and sent by FTP to my remote host,
so such problems will not happen.
