# Troubleshoot Messaging Tables Disk Usage Warnings

In rare situations you may see a disk space usage warning at the command line after running the `rmtadmin status` command:

Internal RMT messaging tables total disk usage is now: <nn.nn> KB.

A message displays when disk space reaches or exceeds the warning threshold of 4 GB.

The database usually cleans up unnecessary tables automatically, but if this warning displays, take the following steps to clean up the tables manually:

1. Stop RMT Server:
    
    rmtadmin stop
2. Start the database service:
    
    rmtadmin start --db
3. Clean up the unnecessary tables:
    
    rmtadmin query "DROP SCHEMA hangfire CASCADE;" --outfile=drop\_hangfire\_schema\_output.zip --commit
4. Start RMT Server:
    
    rmtadmin start

## Who can do this

You need to be a Resource Monitoring Tool Administrator in order to run the necessary commands.
