Extra Long time to solve block

Hi,

I was wondering if anything occurred within the network which might required a mandatory upgrade or something?? It’s been almost a month since my last block has been solved in my private mining pool (using uNOMP) and by my calculations my total mining hashpower should be solving them on about a 6 day average against the current total network hashrate/difficulty.

I’ve experienced long rounds before but this just seems a bit too long …

Thoughts?
