I am testing the cmp disable with vCPU=2 tomorrow as I am not certain demoting a virtual server to tmm0 will disable threaded execution across tmm0.1/0.2/...

Disabling CMP is a successful workaround. We went back to vCPU = 2 and disabled CMP on the virtual server and all our RDPw/SSO connections are still working.

F5 have come back to us on this issue. Enable the virtual on all VLAN's. Updated solution posted.
