Tcpdump on master(A.A.A.A) shows the following:
23:59:54.788272 IP A.A.A.A.domain > C.C.C.C.domain: 26512 notify [b2&3=0x2400] [1a] SOA? mydomain.com. (72)
23:59:54.788898 IP C.C.C.C.domain > A.A.A.A.domain: 26512 notify Refused- 0/0/0 (26)
So it looks like master did sent notify out but refused by BIND slave
B.B.B.B; # public IP of first DNS slave(windows DNS)
C.C.C.C; # public IP of second DNS slave(Linux BIND DNS)

Good. Manual intervention works.
I suggest you try to determine the following from your logs
on both master and (Linux) slave.
Whether the master is sending the NOTIFY.
Whether the slave is receiving the NOTIFY.
Whether the slave is acting on the NOTIFY.
That should make it clear what's not happening without
