Elasticsearch 6.8 is very old and has been EOL a long, long time, so I would recommend that you upgrade to the latest version. Have personally not used that version in a long time so can not recall any common causes for this. Some additional information would be useful though:

- Do you have any type of monitoring in place?
- What is the size and specification of the cluster?
- Is the cluster under heavy load when you see this error? Do you see any evidence of long or frequent GC around the times the error occurs?
- How much data in terms of shards and GB on disk does each node hold?
- Are you using any third-party plugins?
