can you report the issue on github?

it's a little bit hard if the coredump can't be generated. The root cause identification will be taken time.

can I write any script to copy data from s3 and ingest to new starrocks cluster?

yes, you can use bin/meta_tool.sh to dump the data into human readable format and regenerate it to csv or parquet format , and then ingest into a different cluster.

can please help with sample command or documentation?

sr itself doesn't have the ability to pull the data back from remote because FE set the latest version to pull from the tablet and the tablet is causing the cn continuously crashing.

no i mean using bin/meta_tool.sh

need to pull the data file back to local, and then provide it the local fs path to meta_tool.
