Cause
- issue post-installation, baseline_engine defect
Environment
- UIM v9.0.2
- baseline_engine v9.0.2
- baseline_engine v9.0.2
Resolution
First make sure the baseline_engine v9.02 probe package exists in your local archive, it should be present.
Set loglevel to 3, and the minimum java heap for the probe to 512 from 64.
Then redeploy the probe-> Select the probe and rt-click to upgrade and just overwrite the existing baseline_engine probe.
Check the baseline_engine log again.

Remove the mapdb-temp* files from C:\Windows\Temp.
The files should no longer be being written to the temp directory.
If the above steps do not resolve the errors:
Contact support and obtain the hotfix: baseline_engine-9.0.2-HF2.zip
- Deactivate the hub-robot watcher service
- Remove the hubs.sds file
- Start the robot
- Deploy the hotfix
- Check the baseline_engine log again to see if the error is alleviated.
The log should then look like this:
Set loglevel to 3, and the minimum java heap for the probe to 512 from 64.
Then redeploy the probe-> Select the probe and rt-click to upgrade and just overwrite the existing baseline_engine probe.
