After encountering the error "DocValuesField "object.attribute" is too large, must be <= 32766" when trying to persist (with Indexing) an object with a String attribute that is longer that 32766, Infinispan totally stop persisting any new entries. Infinispan still appears as healty in Docker and do not produce any additional error.
The "DocValuesField "object.attribute" error can be avoided by not Indexing the problematic attribute, but the "silent crash" of Infinispan is very problematic.
This issue was not happening in the version 12.1.7. After more testing it was present before too.
