MySQL Circular Replication does not throw error, but is not syncing. Any ideas?

We are using MySQL Circular replication (2 servers in a master-slave setting with each other) for an implementation with both servers is different regions. Previously, we had the entire setup running flawlessly, but the VMWare vendor had to upgrade their underlying infrastructure and had us move the sites over to a new infrastructure. They cloned over our entire app including the servers so we had to do next to no configuration on the actual VMs. However, once traffic was diverted over, one of the servers has gotten into a wierd setting where all flags (Slave_IO_Running: Yes, Slave_SQL_Running: Yes, Seconds_Behind_Master: 0) are showing that all is well, but in reality, the Master_Log_File and Read_Master_Log_Pos variables are not changing at all and seem to be stuck (also causing our NMS not to be able to catch this). Same was verified by creating 2 tables, one on each side. Changes on B are appearing almost immediately on A, but the same is not occurring for changes on A to B. We tried debugging it and when nothing else worked, we just got 2 new VMs, tested out replication again and moved the site over. Within 5 hours, we were at the same scenario again. Below are the outputs of Show Master Status and Show Slave Status of the newer servers. On a side note, there is another simple slave that is also connected to db03 that is fully synced and is following db03 diligently, which proves the issue is not on db03 end. Also, the original setup on the older infrastructure is also still running strong.
