Manual Cleanup of the Temporary Folder
Every time you generate content on the Pentaho Server, temporary files are created on the local file system in the /pentaho-solutions/system/tmp/ folder. In some cases, the Pentaho Server may not properly purge that temporary content, leaving behind orphaned artifacts that can slowly build up and reduce performance on the volume that contains the
pentaho-solutions folder. One way to address this issue is to mount the
/tmp folder on a separate volume, thereby siphoning off all disk trash asssociated with creating new content. However, you will still have to perform a manual garbage collection procedure on this folder on a regular basis. You can accomplish this via a script that runs through your system scheduler; it should be safe to delete any content files in this directory that are more than a week old.
