When I run my application with hazelcast and check distributed object on the application or on man-center I saw a strange map(c95b3d56...) even I did not create or pre-defined map.

strange cache

Is there any advice what it could be and for what.

Below configuration is used in the application and no programmatic config.

<?xml version="1.0" encoding="UTF-8"?>

<hazelcast xsi:schemaLocation="http://www.hazelcast.com/schema/config hazelcast-config-3.8.xsd" xmlns="http://www.hazelcast.com/schema/config" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

Can you please share your Hazelcast cluster configuration, including the programmatic ones if any?

If it's any help, "c95b3d56-2045-4fad-831e-34d0480021b9" is the string representation of a UUID.

Hazelcast doesn't create any distributed maps internally. Also, the map you mentioned isn't seen in your configuration. This means it should be created by calling HazelcastInstance#getMap() API. Please check it if it is called in any part of your code, including the libraries that you are using.

Try adding a DistributedObjectListener. This will alert you to exactly when the map is created. Not why or where, but it will help localise.
