Hello!  
I am using Sonatype Nexus Repository Manager  
OSS 3.49.0-02 with embedded OrientDB. I started to analyze the potential cause of repetitive application errors that occur even after scaling the host to 32GB RAM, with the settings compliant with [nexus requirments document](https://help.sonatype.com/repomanager3/product-information/sonatype-nexus-repository-system-requirements):

```auto
-Xms6G
-Xmx6G
-XX:MaxDirectMemorySize=15530M

```

It turned out that the sum of blobs from individual repositories exceeded 147,000, with the allowable database limit of 100,000 objects.  
So I started cleaning the repositories from obsolete objects, but it turned out that I can’t clean the group repositories. Moreover, the number of objects and their size in the group significantly exceeded the sum and size of objects in the repositories it grouped.  
Using the npm repository as an example:

 ![npm_group_repo](https://canada1.discourse-cdn.com/flex047/uploads/communitysonatype/original/2X/4/4d243343c66a6b7b1dc1bb461ebdf10206c9378c.png)  
_ **npm** is a repository grouping the **npm-hosted** and **npm-proxy** repositories_

Cleaning and compacting individual repositories did not affect the number and size of the grouping repository.  
Therefore, I have a question: Why do the number of objects in groups exceed the number of objects in grouped repositories, and how can I purge grouping repositories?
