Apparantly pushpool requires a minimum difficulty of 256 to work 100% properly, so I attempted to increase the difficulty (from ~45) to 256 or higher so that I could fully test pushpool on testnet before making any errors on the real blockchain.
I should have known this would not be possible since the bitcoin protocol has some sort of difficulty increase limiting factor built into it by default, does it not?
I am curious... did testnet just hit (or almost hit) that difficulty increase limit? It's surprisingly close to a 4x increase right now (sitting at ~175 difficulty).
If anybody wants to join me in upping the testnet difficulty over the next few days, feel free!
