Intermittent connectivity to management IP address on vCMP host but not guest on Viprion Chassis

I am having connectivity issues to my vCMP host management IP address I but the guest management IP address is OK.

The funny thing is that I connect to the guest via the same physical management interface as with the host but network connectivity to the guest is fine but network connectivity to the host is very intermittent; I lose connectivity for hours, it comes back for up to 5mins and the I lose it again.

The setup is a Viprion 2400 chassis with a single B2250 blade, so one slot is populated and 3 slots empty.

The Viprion is running a single vCMP guest at the moment and i have configured it to use all slots. I have configured a host cluster management IP address and a individual management IPs for each slot and similarly a cluster management IP and individual management IPs for each slots for the vCMP guest.

I have no problem accessing the vCMP guest cluster management and individual management IP but I intermittently lose access to both cluster management and individual management IP for the host.

I have raised a call with F5 support but awaiting their reply.

Any help would be appreciated.
