</div></div>thats a desktop board, right? so it probably doesn't have ECC or any of<br>
the other system integrity features of a server board, nor do they<br>
usually have the IO bus bandwidth to handle substantial IO workloads.<br>
<br>
PCI bus errors are not a good thing at all, either. you have 5 ethernet<br>
adapters in use? what sort of Ethernet controller? I believe those<br>
PCI Bus errors are being reported by your ethernet adapters, and could<br>
be the result of excess bus contention. a single gigE can way more than<br>
saturate a 32bit 33Mhz PCI (parallel) bus. All the PCI slots on a<br>
desktop board like you have are on the same bus and contend for the same<br>
bandwidth.<br>
<br>
Also, as mentioned thermal problems are a definite possibility, although<br>
Intel CPUs tend to self-throttle if they get too hot, the Chipset might<br>
not be that good at it (eg, watch the chipset and memory temperature as<br>
well as the CPU). Another possible cause would be silent memory<br>
corruption although that would be more likely to cause a kernel fault<br>
("Fatal kernel error - system halted") however if your display is in a<br>
GUI mode, you won't see this unless the console is directed to a serial<br>
port which is being monitored.<br>
