Not sure, do you still get:

"ioctl SIOCDARP: Network is unreachable" ?

Sounds less like latency and more some kind of network setup issue

No that one is not showing up "ioctl SIOCDARP: Network is unreachable" ?

Here it is in full.

Not sure whats going on, looks like the host drops the connection
as soon as it starts sending periodic packets (it gets through setup OK)

I set up a new system on a Raspberry Pi4, installed a new CAT6 cable and I'm getting the same errors as I received with my previous machine I was testing on.

Here is the startup/shutdown log and the results of halcmd show param *.tmax

I don't think a RPI4 can manage a 1 KHz servo thread over Ethernet
I would try 500 Hz = 2 ms =2000000 ns

I tried

SERVO_PERIOD = 2000000

with P=500 for all 3 axis

Same errors.

Just noticed that while LinuxCnc is running CR4 and CR6 are green. When I exit out CR5 and CR1 turn on. Not sure if that means anything

CR1 will be lit if you get a watchdog bite on the 7I76E
so is expected if you lose communications after the card
is setup by LinuxCNC

If you ping the 7I76E, do CR3,CR4,CR5,CR6 count up?

What are your ping times?

Also since you have very similar symptoms
(communications dropped in the first few servo thread cycles)
on different hosts, it does suggest a 7I76E issue,
so returning the card for evaluation is probably a good idea
