This happens when using the default multicast cluster member discovery process to form the ActiveSpaces cluster.

Note: Multicast discovery (tibpgm) mechanism got deprecated and this feature will be removed in future releases.

To resolve this issue ,switch multicast to unicast cluster member discovery process.
Unicast discovery uses the TCP protocol.
Set the discovery and listen property  "be.engine.cluster.as.discover.url" , be.engine.as.listen.url as tcp://ip:port[;ip:port]*/

For eg:
be.engine.as.discover.url= tcp://IPAddress:5555
be.engine.as.listen.url= tcp://IPAddress:5555-*/
