I am upgrading GemFire from 8.X.X to GemFire 9.5.2. I am using spring-data-gemfire, version 2.1.9.RELEASE.

When I start the service, the first service within the cluster comes up fine. However, the second service simply hangs. I don't see any exception in the service of the GemFire logs.

Has anyone faced similar issue?

We haven't changed any properties, which we were using in the older version. I wonder why it doesn't work with new GemFire version?

Keep in mind that you're doing a major version upgrade (8.X.Y to 9.X.Y), so backward compatibility is not fully guaranteed. I'd suggest to go through Upgrade from Version 8.2 to Version 9 and make sure you haven't missed anything.

Moreover, and according to the Spring Data for Pivotal GemFire Version Compatibility Matrix, spring-data-gemfire-2.1.9 is not listed as fully compatible with GemFire 9.5.2, you should stick to that matrix and avoid overriding the version provided by spring-data-gemfire.

If the above still doesn't solve the issue, you should probably set the log-level as fine and take some thread dumps from the stuck member to see what's going on.

Cheers.
