This is usually caused by misuse of JIRA indexing API: plugins update the issue only but trigger a full issue re-index (issue with all comments and worklogs) issue re-index instead of reindexing the issue itself. Given that we enforce FULL compatibility for our Avro schemas, we generally do not face problems when evolving our schemas. But not using it at the right point.
