Couchbase Server Kubernetes

HI

We are observing frequent corruption of .index files after migration to Couchbase 7.2.The indexer service crashes while reading the .index files.
Post multiple attempts of deleting/clearing the .index files indexer service is able to come up successfully.
Similar behavior was not observed for COUCHBASE 6.6

Snapshot of COUCH UI LOGS

Service ‘index’ exited with status 2. Restarting. Messages:

This isn’t my department, but from this query,
https://issues.couchbase.com/issues/?jql=text%20~%20"\“indexer.go%3A\”%20\“Service%20‘index’%20exited%20with%20status%202\”%20handleWorkerMsgs%20handleStorageRollbackDone"
I find several jira issues, but they are all from QE of unreleased future versions.
MB-55061, MB-55077, MB-55284, MB-55317. They are probably not public. I suggest you open an issue with support for investigation.
