SB freezing when scraping

Hi Guys,

I am using SB v2,

i have SB running on a dedi server tons of RAM and CPU

i have 150 semi dedi proxy's

my issue is when scraping (with any of the SE'S) after an hour sometimes less the links per second go down to next to nothing i have tried using every SE it happens with them all.

i have gone as low as 10 threads

with some engines ask.com etc i am getting 700k+ links and then it just stops.

it runs super cool and then just nothing.

Any help will be great.
