OperationTimeoutException in Hazelcast 5.2.2

[Raihan Al-Ekram]

We have recently upgraded our Hazelcast platform version from 3.12.13 to 5.2.2. After the upgrade we are facing: com.hazelcast.core.OperationTimeoutException GetOperation invocation failed to complete due to operation-heartbeat-timeout.

We use a two node Hazelcast cluster. In our Java application code we use several IMaps. The exception is always happening while performing a get operation on one particular IMap. This happens around the same time a node is also performing remove operations on this IMap. It is possible that the key for both the remove and get operations are the same. The application ran fine with 3.12.13. Is there any difference between the versions that may cause this operation timeout?

Is it possible to have a reproducer? This seems something unexpected.
