cgminer --load-balance, Is there limit to number of pools?

[Wave_of_Mutilation]

Greetings!

I'm trying to bunch a couple of pools in balance, to prevent stucks of getwork.

I have discovery that 7 pools works well, but more than 8 pools stucks.

Anybody know how to better bunch many pools with cgminer?

Code:

./cgminer -q --scrypt --gpu-platform 0 -T --no-submit-stale --queue 4 --scan-time 1 --intensity 11  --thread-concurrency 2048 --load-balance  \
        --url stratum+tcp://pool1:9000 --user username --pass password \
        --url stratum+tcp://pool2:9000 --user username --pass password \
        --url stratum+tcp://pool3:9000 --user username --pass password \
        --url stratum+tcp://pool4:9000 --user username --pass password \
        --url stratum+tcp://pool5:9000 --user username --pass password \
        --url stratum+tcp://pool6:9000 --user username --pass password \
        --url stratum+tcp://pool7:9000 --user username --pass password \
        --url stratum+tcp://pool8:9000 --user username --pass password \
        --url stratum+tcp://pool9:9000 --user username --pass password \
        --url stratum+tcp://pool10:9000 --user username --pass password
