Greetings. Every couple of day's I have a web server running CentOS 4.1 with all the patches as of Saturday that is crashing every couple of day's. Usualy between 4-6 am. The Console shows: Double Fault gdt at xxxx memory Double Falut tss at xxxx memory On reboot all is fine. It's running apache and DNS no SSH access. It passes memory test Memtest86. I can provide more information if you direct me on what to send. Thanks -Jay
