What is happening here (and I am basing my conclusion on the logs) is a loop across VLANs.

Let's examine this log message:
04/12/2015 12:56:52.04 MSM-A: Advert for VR on vlan V2303D vrid 1 ignored: couldn't find VIP 10.132.0.254 in VR's list

What this log message is saying: for the VRRP instance in VLAN V2303D, the IP 10.132.0.254 is outside its subnet. It looks like VRRP packets with VIP of 10.132.0.254 are making it to VLAN V2303D some way. To me it looks like V2300D is somehow looped into VLAN V2303D.

Most of the times these VRRP warnings are caused by a L2 loop, ELRP would send Multicast packets to detect the Loop, in case some devices like IP phones does not flood the multicast packets ELRP would not detect a loop even though there is a loop, so tracking the cables would help to find the loop.
