Problems with HA and CARP

[iranrl]

Hello,

I have 2 PFSense boxes in my branch, two months ago the main box presented routing problems (something in the operating system that I could not understand clearly) and it was reinstalled, I left the secondary box in production I reinstalled the primary box and synchronized with the secondary , after this procedure I configured the newly formatted box to primary, I successfully performed failover tests.
Two days later, I restarted the primary box, after the boot the CARP IPs did not migrate completely were half the primary box and half in the secondary box (according to figure), I suspect that the synchronization from the secondary to the primary generated some problem but I could not find Nothing concrete has anyone had a similar situation?

Sorry for bad English.

PFSense 2.3.3 amd64
