I'm seeing log messages about the failure to send audit log message while running the Sandbox. What's wrong?
If your computer goes into sleep mode, then you may see these messages after the machine is restored from sleep mode, as the audit logs are not getting delivered while the machine sleeps. You may need to restart CDAP to restore its state depending on how long it has been asleep.

You can use the CDAP User GoogleGroup to report issues or file a ticket using the available CDAP JIRA system.
