Random SER freezes during manual verification of 60k links, 14 projects

At 8.40, 14 active projects, my SER would randomly freeze for 0.X-7 seconds with no apparent reason during manual verification of 60k links. Mostly in 0.x-2 sec range.

CPU stays no more than 20%, avg. 10, memory no more than 1.2Gb, avg. 300. Threads fluctuate 200-500 at 800 setting. B/W stays at 100-150 mbit from 1Gbit with 250 guaranteed so its likely not that.

Log skips those seconds and all other applications [CB] are responsive which means it is not RDP. Server is pristine, not even Adobe flash is installed, only SB, SER, CB, Opera.

Anyone experience this behavior?

    Just for information in case somebody happens to land here, to end topic "on major note":

    Studied problem for a while, It seems like DNS-related problem. I've not entirely nailed it yet, but things to try if you have something related include:
    • Monitor Events log to narrow scope of the problem
    • Flush DNS and try to compare performance
    • Change DNS
    • Latest Driver For Network Adapter
    • Disabling the DNS client in services control panel
    • Installing/Uninstalling system updates.
