maximum number of lan interfaces supported

[bongo]

i'm actually trying to setup opnsense on a new hardware,
i want to use the onboard ethernet for wan, and inserted a lan card to each of the 3 pcie slots of the mainboard to serve 3 physically independent lan networks.
unfortunately, opnsense seems to recognize only 2 of the inserted ethernet cards, i.e. no matter how i assigne the cards to the pcie slots, i always get re0, re1, re2 but no re3.
am i doing something wrong or is there a limitation?
i haven't found appropriate info in the doc.
thanx!

btw:

when have the configuration:
1 onboard ethernet,
2 pcie ethernet,
1 usb ethernet,
i can see 4 interfaces in opnsense (re0,re1,re2,ue0)

but with:
1 onboard ethernet,
3 pcie ethernet,
i see only 3 interfaces in opnsense (re0, re1, re2)
although there are also 4 physical interfaces available.

what's wrong?

for no known reason, after several reboots, suddenly, all interfaces on pcie cards are shown (without changing the hardware)

I have a system with 6 dual nic cards

This maybe outdated,
But recently i have same problem, i've been using lan card with 4 port of LAN. opnsense only detecting 3 port, there are one port missing. And also BIOS in my motherboard not detecting one of two RAM Slot (bios only detecting one RAM Slot)

Long story short,
there are couple of needles on the processor slot at motherboard are not properly stiffed. It is so small, i have to use magnificent glass to see it. After i made them proper using 2 sewing needles then everything is back to normal.  If you have this symptom, it's better check, to avoid problem when its operate in the future, for some reason if the processor getting hot those needle on the processor slot could be not stiffed as it suppose to be.
