Resolution

• There is no way to determine if this was manual or an OS restart based on this error
• You have to check OS event logs to see if there was a system restart during that time
• Also this may have been done by someone directly or indirectly (via the command or via scripts)
• Review the bg-system logs for any clues
  • If you have an OOM error then:
  • Check if you have set up heap dumps on OOM on BG in properties.xml (provide if needed) Check if any got generated in the indicated directory on those times
