Temp files generated by Yum repos during a group metadata merge are not removed after the merge is completed.
1. On a clean 3.35 instance, create a set of yum repos/groups with the following structure against the default blob store:
2. Check the <sonatype-work>/blobs/default/content/tmp directory and observe it is empty.
3. Make a request for the repomd.xml via top level group e.g.
4. Check the <sonatype-work>/blobs/default/content/tmp directory again and this time observe several temporary blobs exist all totalling ~54mb which have not been removed.
These temp files should be deleted after the merge request completes.
Stop Nexus and manually delete the temp files.
