Hello  
We had an issue with our OSS Nexus 3 ( nexus-3.20.1-01 ) production issue.

It was frozen, the gui was not responding and it was not willing to shutdown even after multiple attempts and giving it several minutes each time.

We decided to kill the processes. It took kill -9 to finally kill it.

After that it never came back up it was blocked at this step

I looked at previous logs and it should have gone to these steps

It never timed out or gave real errors or exceptions. Seems like the scheduler never got ready to start and just blocked

We decided to restore a backup but it has also caused other issues.

Best regards

There’s not a lot to go on here as (as you hint) the log snips you show just show INFO messages, nothing out of the ordinary.  
My general recommendation is to review [System Requirements](https://help.sonatype.com/repomanager3/installation/system-requirements) and make sure your system is up to spec.
