Machine check exception is when you see something like this in your logs:

Jul  9 12:19:41 vz01 kernel: CPU 0: Machine Check Exception: 0000000000000004
Jul  9 12:19:41 vz01 kernel: Bank 4: b604a00100000813 at 000000007e4f2f68
Jul  9 12:19:41 vz01 kernel: Kernel panic: CPU context corrupt

What does that mean?[edit]

Such messages are printed when the CPU detects hardware problems, e.g. memory corruptions or some other problems. It is 100% hardware problem with your server.

What to do?[edit]

The best thing to do is check your server — see Hardware testing.
