I have an issue with cgminer 2.9.x (I switched from 2.8.7 to 2.9.3, now I'm with 2.9.4).
My system has two 7970s. Usually it's capable of about
19 shares/minute. "Difficulty-1 shares", I mean.
I have many pools in my configuration file, and I use
fallback policy.
Well, now I'm switching to my pool 0, rpc.hhtt.1209k.com, which is tuned for "difficulty-999 shares" (I find about one "difficulty-999 share" per hour).
See the log:

Since I'm coming from pool 4, let's discard the first shares still going to pool 4 (till 10:36:54): that's normal.
In minute 10:37 there are no shares found, which is normal too (difficulty 999). Then I start to find and submit shares also for other pools. This isn't normal, IMHO, and surely it has never happened before 2.9.x. Of course,
when a new block is found, very few shares always go to different pools: but now
a lot of shares (1 - 5 per minute, so
up to 25% of my mining power)
sistematically go to other pools, which I don't like: they're prop pools running long rounds, or simply backup PPS pools with higher fees (or lower efficiency) that should come in play only when my primary backup pool (pool 0) isn't available.
Am I missing something? Is this behaviour intentional? Why?
Thanks.
