Environment

Resolution

Command used to launch Analytics backend in the service manager can be found by right click on Analytics backend service manager dialog and click on properties

 "C:\Program Files\Java\jre1.8.0_241\bin\java -Xmx3096M -jar analytics-backend.jar"

We need to verify if there is enough physical memory on the server. In this case, it was 15 GB

We increased the  maximum memory allocation pool for a Java virtual machine to 4096 as follows in the command used to launch Analytics backend in the service manager

"C:\Program Files\Java\jre1.8.0_241\bin\java -Xmx4096M -jar analytics-backend.jar" 

After restart the Analytics backend the problem was solved
