This server was running fedora core 2 till 12/2/2005. It had an impressive uptime of 180 days or so. On friday I upgraded to CentOS 4.2. After upgrading to CentOS 4.2 this server has been throwing kernel panics every 10 hours or so.
These are some of the error messages I am getting on the console: "CPU 0:Machine check exception :4 Bank 0 : f672100000000833 TSC 112180365ccf ADDR e2c7f7c0 Kernel Panic - Not synching Machine Check"
This is a production server. I would appreciate any help.

2 things I would do first is to check both memory and cpu cooling.

agrred. Try downclocking the machine, running memtest86 and then switching cpu/memory chips/motherboard/power supply/fans/cooling in roughly that order (based on what you have available). This looks very likely to be hardware related (unless you have a very unusual set of poorly supported hardware, but that seems very unlikely). Cheers, MaZe.
