Sometimes between August and September, and it was on Suse Linux Enterprise Server 12. The lines would go missing mostly if the logs were collected two or three days later instead of immediately after the job finished (it was a job running for 24 hours), which leads me to think it had to do with journald expiring entries to save on disk space. A consistent log manager would expire them chronologically, but here the lines were missing from the middle or the end of the output, so not the oldest ones logged.
