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?
