we are using Denodo from Azure market place. Everyday VM need to shutdown and restart when required. Once the VM is started, the services for Denodo becomes up and running. But when trying to connect with vdp it is giving this errror: *authentication error: Database 'admin' not found*. Restarting the services solve this problem but this issue should be solved. I have also checked the memory status (as suggested in some answers) and it is looking good.
When I have checked the Denodo VDP logs it is giving this info:
*ERROR 2020-12-04T02:19:48.328 com.denodo.vdb.engine.session.DBSession  - Unable to obtain metadata connection: Cannot create PoolableConnectionFactory (Failed to start database 'dbmetadata' with class loader sun.misc.Launcher$AppClassLoader@75b84c92, *
Any idea to solve this issue.
Thanks a lot.
