A recent experience - might be related or not:
We have seen similarly weird behavior when (due to a firmware bug) multiple devices of the same type were using the same MAC address. IP addresses were statically configured and correct.
The switch (that the devices were connected to) was updating its arp tables every ~10sec, and we saw StreamDevice connections timing out then reconnecting to a different device.
Of course, any tests with a single device were always working just fine.
Cheers,
