Issue with AEM Author ACC Indexing

Hello,

----

The scope is an AEM author on premise instance. 

----

we seem to have a SegmentNotFoundException on one of our AEM author instances (integration/test layer)

This error causes indexisng not to work properly on the instance, which has impacts on

1) page moves (link rewriting does not work

2) the Lucene search functionality (some of our custom code is also impacted.

I tried to follow the usual steps:

- https://experienceleague.adobe.com/en/docs/experience-cloud-kcs/kbarticles/ka-16542

- https://github.com/cqsupport/fix-instructions/tree/master/count-nodes

----

the normal check fails immediately with an exception:

[aem@xxx-xxx-aema1 crx-quickstart]$ java -jar oak-run-1.10.6.jar check --bin=1 repository/segmentstore

Apache Jackrabbit Oak 1.10.6

org.apache.jackrabbit.oak.segment.SegmentNotFoundException: Segment 39523625-57bf-499d-a39e-f82c4f584cd9 not found

at org.apache.jackrabbit.oak.segment.file.ReadOnlyFileStore$1.call(ReadOnlyFileStore.java:124)

...

----------------

The check passes without finding ano problem IF we specify the "--head" option

(last good revision reported as a half an hour old -> fine, as instance was shut down for about that long)

[aem@xxxxx-xxx-aema1 crx-quickstart]$ java -jar oak-run-1.10.6.jar check --bin=1 --head repository/segmentstore

------------------

Is there something else we could try before we have to create a content package, then recreate that instance from scratch?

Thanks,
