netstat -an output, pls. explain..

Hi,

I have old SCO O/S. System keeps crashing. I made lot of changes to kernel but so for nothing helped. I wrote a script which takes netstat -an output every one minute. I saw some thing right before the system crashed. Not sure if this means anything..

Code:
 
uname -a
SCO_SV djx2 3.2 5.0.6 i386
 
Netstat output is huge, I am just cutting & pasting from the end....

What looks strange to you? This does not appear to be sufficient. We also don't know what you are doing in your script Are you concerned about the null characters?

Thanks for your reply. Yes. on the above you see all the NUL. I never saw that until today. Does that mean anything. Below you will see the output from netstat -m. This has more info. Does this mean anything. It's SCO UNIX, we will upgrade to Linux but for now, I have this system. I have to find why the system keeps crashing every day.
