OK, like zombie I'm using 6.10.58 on all my systems. I have not done surveil but with FH & WUProp I have never run into Zombie's network problem within BOINC. I have seen something similar but it is related to Win7 on my primary desktop when RAM utilization (It has only 3GBs) is upwards of 80%. That is because of apps not related to BOINC.
