This problem obviously needs to be fixed.
I would like to ask those who have an AHA-2940UW to try the following test
and see if any work correctly. I get the error every single time.

I have two directories, say dir1 and dir2 with dir2 empty and dir1
having size 360 MB.

Whenever I do a
cd dir1; tar cvf - . | (cd dir2; tar xvf - )

I get the broken pipe error after around 200 MB transferred.

Thanks,
