We are continuously getting below Debug level log as of now I'm not sure it will cause any issue...
2022-01-27 16:13:55.705 Debug: IndexerEnv::putRangeIndex: XDMP:parent link :invalid parent link node doc("xx/xx")//xx
2021-01-24 16:13:55.715 Debug: IndexerEnv::putRangeIndex: XDMP:parent link :invalid parent link node doc("xx/xx")//xx
Can anyone help how to resolve this and it will create any performance issue?
It would appear that you have a fragment, but the document for that URI is missing.

Message Text
Invalid parent link node doc("variable1")//variable2
Cause
A parent fragment in a fragmented document is missing.
Response
The document must be reloaded.
You may need to look and see what sort of fragment it is (document-properties, document-lock, or if you have fragmentation rules to split documents into multiple fragments) and the history of changes for such documents.
