Hi all,

running 6.1-RELEASE on several HP DL385 servers (identically
configured), one of them has recently spat the following out in the /
var/log/messages file:

NMI = non-maskable interrupt, if I remember correctly. However, I
have no idea what this means or why it appeared. The status light on
the front of the server has lit up red, as opposed to the usual
green. All services on the host are running and behaving normally
from what I can tell.

I suspect you'll find your (ECC) memory has problems.

You are absolutely correct. Further investigation using the ProLiant management tools for FreeBSD revealed serious RAM trouble. Two banks were degraded, so we have now had the modules replaced on-site.

Thanks for the tip!
Do you happen to know if there are any "generic" tools/daemons available to decipher such NMIs? Perhaps be able to send SNMP traps or something?
