Hi!
I am (still) struggling with crashes.
I now suspect, even more, netrom has to do with the crashes, latest hint
is this:
From /var/messages I can se one user logging in to dxspider who
probably has come over so many 1200 bit/s nodes that it cannot pass the
traffic fast enough, but a (netrom transport) queue is built up.
After 1,5 hour of connection, the node is crashing.
- Maybe due to filled up queue (not liekely)?
- Maybe due to a disconnect from the remote end with a large queue?
Below is the tail -f of the log file as seen over 1200 bit/s, including
the disconnect after the crash:

[sm7gvf@pc2 sm7gvf]$
kernel 2.4.22-pre10
HR6.1
Guessing here (the system is down):
libax25-devel-0.0.7
libax25-0.0.7
ax25-tools-0.0.6
ax25-apps-0.0.4
running dxnet, fbb, dxspider, node0.3.0
I am using the script below as startup, I don't have all the other files
at hand here.
Could it be netrom causing this?
What more information could I supply?
