1.2GB (!), 256k cache per ( :( the 0.18u coppermine xeons are only available
this way), and RedHat Linux 6.1, special Dell SBE version.

yeah, ugh. Well, the system came with 256MB of PC133 ECC registered SDRAM
(2 * 128MB), I've fortified it with an additional 1GB of PC133 ECC
registered SDRAM (4 * 256MB). I would *hope* any memory error would trip a
ECC error. Tomorrow, I might pull the 1GB out and leave just the original
256MB to see what happens...
Lets see whether a single instance runs all night... If it does, then I'm
gonna have to suspect a cache coherency problem which is likely
architectural, ugh. This machine uses the ServerWorks III LE chipset
(formerly Reliance Computer Corporation, they make high end SMP server
chipsets for Compaq, Dell, HP, SuperMicro and others).
