Background

The database performs a log rotation once a day. By default, this happens at 4:00 AM.

Description

If an IMPORT or EXPORT statement using a JDBC driver starts around the time the log rotation takes place, the statement may fail with the following error message:

ETL-5402: JDBC-Client-Error: Failed to initialize Query: Internal server error. Please report this. Transaction has been rolled back.

Workaround

Re-run the statement at a later time. 

Fix

IMPORT and EXPORT statements run normally, even during log rotation.
