Regular realtek fast ethernet. Each one connected to a broadband modem (1 Mbps each) so I do not think this should be a bus saturation.
I do not think this is a thermal problem due to the lack of messages (I got this problem in the past with a different machine and I got those overheating message - with the throttle but I'll investigate further.
I'll remove the gui mode to try to catch those errors.

PCI bus errors are not a good thing at all, either. you have 5 ethernet
adapters in use? what sort of Ethernet controller? I believe those
PCI Bus errors are being reported by your ethernet adapters, and could
be the result of excess bus contention. a single gigE can way more than
saturate a 32bit 33Mhz PCI (parallel) bus. All the PCI slots on a
desktop board like you have are on the same bus and contend for the same
bandwidth.
Also, as mentioned thermal problems are a definite possibility, although
Intel CPUs tend to self-throttle if they get too hot, the Chipset might
not be that good at it (eg, watch the chipset and memory temperature as
well as the CPU). Another possible cause would be silent memory
corruption although that would be more likely to cause a kernel fault
("Fatal kernel error - system halted") however if your display is in a
GUI mode, you won't see this unless the console is directed to a serial
port which is being monitored.
