Still having shares stop submitting after ~20 minutes like clockwork. No actual freeze with cgminer, just shares no longer get submitted at all, even as it continues to hash away.

Is no one else experiencing this? It's not on my end, I ruled out pretty much every variable, tried different versions of cgminer, et al. Something had to have changed server side, and it affects uswest, useast, and eu at the least (I didn't try asia). Tried a different address- same deal.

Meanwhile testing on other pools and it's fine. Hashcows for instance has no issues as far as this symptom goes.
