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?
