If it's CentOS 4.x you could setup a netdump server so if there is a kernel panic it writes it to the server.
If it's CentOS 5.x netdump was replaced with diskdump as far as I can tell, you can see an overview here:

Assuming it is causing a kernel panic, it could just be faulty hardware freezing up(bad ram etc).
In my experience this is the only way to get info out of a system that freezes in this fashion, log events that point to the cause are extremely rare.
