A single pair of brokers in an HA replication is insufficient to prevent a split brain. There are several different configurations that can mitigate split brain, for further details see https://activemq.apache.org/components/artemis/documentation/latest/network-isolation.html#network-isolation-split-brain Regards, Domenico On Wed, 1 Oct 2025 at 14:45, Gunawan, Rahman (GSFC-SEWP)[Halvik Corp] <[email protected]<mailto:[email protected]>> wrote: Hi, I set check-for-active-server to true but when the primary shutdown, the backup becomes primary. However; when I started the primary server that was shutdown, it became active, not checking if there are any active servers so it cause split brain issue. Attached is the broker.xml.
