Download as zip wastes disk space

[GCocchella]

I'm running Alfresco Community v5.2.0. When an user select files and click on "Download as Zip", this creates bin file on disk that they are never deleted. Googling, I've found https://issues.alfresco.com/jira/browse/MNT-20212 that seems the same problem I have. 

Browsing the nodes, I have 2 sys:downloads nodes: one is workspace://SpacesStore/downloads_container and the other is workspace://SpacesStore/c04a4e4d-a8b4-425b-9c62-dd7a7752aa06, where the uuid is depending on the alfresco installation.

If I "download as zip" using admin user, the file is created under workspace://SpacesStore/downloads_container; if I "download as zip" using a standard user, the file is created under workspace://SpacesStore/c04a4e4d-a8b4-425b-9c62-dd7a7752aa06

Looking at the permissions, my two sys:downloads nodes has the same permissions than the ones reported in the bug MNT-20212. Now, I'd like to avoid a fresh installation... but how can I modify the download cleaner in order to clean workspace://SpacesStore/c04a4e4d-a8b4-425b-9c62-dd7a7752aa06 too? I do not know and it's not written in the bug fix...

May be I can solve the problem changing the permission of workspace://SpacesStore/downloads_container but I don't know if it's easy or not... I think it isn't because otherwise the MNT-20212 would have reported it.

Waiting for support... thank you!
