If you look further into the detailed logs, you might see something similar to
INFO: Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x0000000080000000, 1082130432, 0) failed; error=’Cannot allocate memory’.

You encounter this error because the system is running out of memory.


This is a known issue as per the Oracle Support Document 2381969.1 (OAC : Oracle Analytics Cloud Backup Operation fails [OBI-LCM-99999] An unknown or unexpected error occurred: Error Occurred during Export: Operation Failed), and Oracle is investigating the memory consumption issue.

You have two options now.

Option 1: Go to Cloud console and stop the OAC service. Once stopped, then start the service.
Remember: do not stop and start the service via scripts. This will not release the memory.

Option 2: Scale up the service instance.
