MCA
HARDWARE ERROR. This is NOT a software problem!
Please contact your hardware vendorhttps://forum.netgate.com/topic/137932/v2-4-4-crashing-under-load-with-mca-error/6
If the MCE decoded as "internal timer error", the next most likely thing is a faulty CPU or mainboard.

Ok I'll get unit replaced today and see where it goes...
-
I went back to the vendor and got the same unit replaced, but it still be crashing after few minutes.

Then maybe it's a memory (RAM) problem.
Because the error is the sameMCA: Bank 3, Status 0xfe00000000800400 (0000 0100 0000 0000)

Ok I'll try replacing the ram and see...

@manjotsc
Perhaps the problem is not in memory
This error has long been known , but whether it is solved - I do not know

Maybe I can't say anything. I don't know the configuration of your hardware other than the processor + 4 lan adapters Intel (igb) + 1 lan adater Intel(em). One thing is clear, this is a problem with the equipment.

100% a hardware issue though the exact nature isn't always obvious as to which piece of hardware is at fault.

We can't do nothing about to find out the exact issue?
I am using the Dell Optiplex 790
-
Your hardware vendor may be able to make better sense of those MCA errors. I'd start there.
-
@jimp You mean contacting dell?
-
If that is who made the system, then yes.
-
Do you have a NIC expansion card in it? Try removing it you have nothing to lose.
At least one of those errors looks almost identical.

I had tired, finally I just swapped the dell motherboard with American Megatrends board. Everything seems to working fine as of 3h 15 minutes of up time...

Thanks everyone above, for helping.
