Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I have seen this error on a system with a Nehalem server motherboard. When it happens, the system freezes and will eventually reboot.

The full error is:

Processor /CATERR (#0x68) Informational event: CATERR reports it has been deasserted. BMC - LUN #0 (Channel #00h)

If you don't know anything about this exact error, I would still like to understand exactly what a "CATERR" is.

I should mention that the server is running a custom linux kernel based off 2.6.18.

A processor CATERR is a CATastrophic ERRor asserted by the processor. As for the error itself, more info would help.

If an “MCERR class” error occurs,CATERR# is asserted for 16 BCLKs.

If an “IERR class” error occurs,CATERR# remains asserted until warm or cold reset.
