Description

A rare race condition can cause IMPORT/EXPORT jobs to fail. It may lead to exceptions like "ETL-1102: Connection to loader service lost" or "ETL-5050: An EXAClusterOS communication error occurred".

This can occur in case multiple ETL jobs are failing at the same time.

Workaround

It is very likely that a retry won't have this problem again.

Fix

The issue has been fixed.
