[plug] Intermittant, constant crashes

[Kai]

Howdy all,

For a while now my 6.2 firewall/javaradio server has been crashing for 
no apparent reason after no regular time interval.
I have been checking the logs I know of and nothing appears to be wrong, 
however, here's a basic run down.

Machine boots fine, no worries....then, maybe after 10 minutes or 3 days 
the machine will unexpectedly stop responding to any keyboard requests 
and only a hardware reset will get it running again. A common time for 
the server to stop responding is about 12 hour or so, but, as I wrote 
before it has crashed anywhere from 10 minutes or 3 days.
That's about it really, for no apparent reason the machine stop 
responding and I can't find any trace of why in the error logs that I 
know of...everything shows as normal.

System is:
Pentium 233MMX with 64 Megs of RAM
Red Hat Linux 6.2

I have used the same machine for a few years now and this has only 
happened in the last few months, I didn't want to bother anyone on list 
before I checked the logs and did some troubleshooting, however, I'm not 
a full bottle on Linux, far from it and any help would be more than welcome

I can hear a lot of people say "wipe that crap off their and install 
Debian", that might work but it won't solve the problem of why this 
machine crashes without any warning.
I am out of ideas and any feedback would be greatly appreciated.

I hope I've provided enough info.
TIA

Kai
