Hello @DIPEN1,
Could you please share some more ERROR messages from the logs which were outputted before/after the message you've provided initially? If any of them contained SegmentNotFoundException, it would indicate presence of repository/segment store inconsistency.
To fix that the following steps should be taken (please see the link for reference):
1. Download a version of oak-run that matches your oak core version from https://mvnrepository.com/artifact/org.apache.jackrabbit/oak-run
2. Run the consistency check,
java -Xmx6000m -jar oak-run-*.jar check --bin=-1 /path/to/crx-quickstart/repository/segmentstore
3. Revert the repository to this revision by editing ./crx-quickstart/repository/segmentstore/journal.log and deleting all lines after the line containing the latest good revision.
4. Remove all ./crx-quickstart/repository/segmentstore/*.bak files.
5. Run checkpoint clean-up to remove orphaned checkpoints:
java -Xmx6000m -jar oak-run-*.jar checkpoints /path/to/crx-quickstart/repository/segmentstore rm-unreferenced
6. Finally compact the repository:
java -Xmx6000m -jar oak-run-*.jar compact /path/to/crx-quickstart/repository/segmentstore/
Regards
