Oracle Coherence - Version and later
Information in this document applies to any platform.


The application uses a distributed cache with Elastic Data and Backup Storage to hold a huge volume of data. The customer is seeing OOME during the backup storage put and after the backup storage file size reached 1GB with the default configuration of the backup-storage. This is expected behavior based on default settings. So the customer has increased the backup storage to 2GB and then the customer faced the subsequent error as given below.  The below three errors were when used with default values, when set to 2GB and then when set to greater than 2GB.
