[nos-bbs] netrom related crashes (INP)

[jerome schatten]

Maiko…

I’ve been following this thread from the beginning… 

Can you tell me a bit about HOW the ‘crashes’ you’re talking about present themselves?

I’m trying to figure out if what you’re seeing and what I’m seeing are manifestations of the same problem. 

On my pi, if one watches my jnos F9 screen and runs ’top’ along with ‘jnos', I see, in almost every single crash, CPU usage goes to 100% for jnos on the ’top’ screen and jnos locks up.  Is this true of the system crashes you are experiencing? Killing jnos from another terminal is the only way out. 

The frequency of crashes here seems quite random… Sometimes a few a week and other times one every few months. When it does occur, I have a pretty good idea of what jnos was up to as the F9 screen freezes and I can trace back to the logs at the time of the freeze. What I see is more often than not, is that the freeze happens during a forwarding cycle.


Thanks,
jerome  VE7ASS
