This is in regards to the LF Server "maintenance" activities for actually deleting files from the volumes once they've been purged from the recycle bin. We do a lot of migration work within a staging environment and then promote to production and it would be helpful to see what's pending that final deletion. And, ideally, a way to manually trigger it, but that's a separate request.
From what I can see, TOC and DOC clear out immediately upon purge so my guess is there's some other table tracking all the files that are ready to be deleted.
