Remove snapshot Repository does not work !!!

Hi,

We have an hosted Repository which contains the snapshot jars/ears created by cruise control.

When we schedule a cleanup of this snapshot repository, nothing happens.

actually nothing is being deleted from the snapshot repository, except the time stamp of -jar.md5, -jar.sha1, -pom.sha1, -source.jar.md5, -source.jar.sha1 are changed to the running time. but the class jar or source jar are not being deleted.

as the storage becomes bigger and bigger, we get some problems with diskspace.
Do I miss something in the configuration? i use the latest version of Open sourcen and tried also the Pro version but still the same.

in attachments you can find some extra info.
