TCP Reset when VIP is Active/Enabled

Hi,

I have a strange issue on LTM vCMP Guest 11.5.3 HF2 A VIP is enabled and active (Green) however inbound packets are reset by the F5.

A TCPDump of the connection using the F5 wireshark plugin shows that the RST was caused due to the VIP being disabled.

RST cause: [1add66c:1592] VIP disabled
Length: 21
0000 000. = Version: 0 (0x00)
.... ...0 = Peer: 0
Value: 0x000001add66c
Line: 1592
Cause: VIP disabled

Could this be a bug as the VIP is clearly active.

Thanks MP
