Problems with system lockup

[kd1zd@xxxxxxxxxxx]

I've been having problems recently with my Linux system.  It randomly locks up, and I was wondering if anyone out there has experienced problems with a hung system.  

My system is CentOS 5.5, and is running UROnode and JNOS.  I have been having segmentation violation issues with JNOS, which I'm trying to figure out.  I have two serial ports which drive TNCs connected to radios.  

When I say the system is hung, I mean that the only thing that will liven it is a hard reboot or power cycle.  Anyone else troubleshoot these issues before?  I'm trying to run a 24/7 TCP/IP node and BBS, but these lockups make it very hard to do so.

Thanks,
