Patrique Legault created OAK-12282:
--------------------------------------

             Summary: PersistentDisk Cache is unbound, with many JCR reads on a empty instance can cause OOM
                 Key: OAK-12282
                 URL: https://issues.apache.org/jira/browse/OAK-12282
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: segment-tar
            Reporter: Patrique Legault
         Attachments: Screenshot 2026-06-25 at 11.25.43 AM.png

The AbstractPersistentCache is not a bound list which in the case of concurrent JCR reads will lead to a flood of items in the List.

 

As we can see [1], the items waiting to be written to the queue are in the billion of bytes.
