I have 5 primary servers on Windows 2008 SP2 on ZCM 10.3.1.

I noticied that the size of the folder %ZENWORKS_HOME%\work\content-repo\content is not equal on the 5 primary servers.

There are little size differences between 4 of these servers, around 1 - 1,5 Gb. but there is a server with more than 10 Gb on this folder than the rest of servers.

I run ZDC tool on all the servers and I get for all of them a good result:

All aliased content objects linked to existing content.
All content objects reference to existing files.
All content files are in consistent state.

How can I delete or check what is wrong in the content folder of this server ?

Thanks in advance
