I have a similar problem...I'm using RH 8.0 and this server is being used for backup. This is a brand new server in quite a cool room. It locks itself , I presume with high CPU usage 'coz I cannot login nor do anything unless I reset the machine. I'm posting the sysinfo for my machine as well and was wondering if somebody out there could help me resolve this.
This has been going on for the past 1 month. The only change I've made is upgraded the RAM from 512Mb to 1024 Mb. Both the 512Mb mem modules are the same config. And I haven't done anything to the swap.. This lock up has been happening even before the memory increase..
Any help would be much appreciated
