Safenet USB SuperPro dongle on AnywhereUSB on server2012R2 unstable connections and BSOD's

We currently run an AnywhereUSB/14 containing 2 Safenet SuperPro dongles
AnywereUSB/14 firmware on the latest release
RealPort driver
SafeNet driver
On both VMWare nodes 2012R2 Servers we encountered instability and spurious BSOD’s
We removed Kaspersky antivirus but that does not seem to help.
The minidumps shows DRIVER_IRQL_NOT_LESS_OR_EQUAL at tcpip.sys+10787f ntoskrnl.exe+1554a0

We have no idea what’s causing the instability. Network connection pings shows no hickups or excessive delays between the machines.

Any ideas?
