It has been reported that CyBlock may stop while proxying machines that are incorporating NIC teaming software.
Removing the teaming software from the machines alleviates this issue. Below, is Wavecrest Computing’s official statement on the matter.
Since NIC teaming is only provided by hardware vendors (i.e., not supported by Microsoft), Wavecrest is currently not providing support for this technology. As a result, Wavecrest may ask that you temporarily disable or remove NIC teaming software when troubleshooting issues where the teaming software is suspect. If the problem is resolved by the removal of NIC teaming software, further assistance must be obtained through the hardware vendor.
