As you guessed, this message happens when the kernel won't give the driver
any memory to receive packets into.
The driver attempts to survive by saving the packets in the local Rx ring
memory, but there is only 32KB or 64KB. Eventually the chip will stop.

What kernel are you running? Some older kernels had a problem with not
keeping enough available memory around, even when they had plenty of swap
BTW, you do have swap space, right? When this happens, do you still have
available swap space?

Hmmm, those kernels shouldn't have the old problem. Check your swap space,
and look for processes running wild.
