---------------------------------------
Hi Gary,
Following is the java code I am using to generate the sample files.
public class CSVUsingLog {
private static final Logger logger =
LoggerFactory.getLogger("auditcsvfile");
public static void main(String[] args) {
int val1 = 9, val2 = 11, val3 = 12;
logger.info("Info Message!", val1, val2, val3);
logger.info("Info Message!", val1, val2, val3);
logger.info("Info Message!", val1, val2, val3);
}
}
I run the same code multiple times to test file rollover. I am using the
configuration mentioned in the description.

> Improper header in CsvParameterLayout
> -------------------------------------
>
> Key: LOG4J2-1482
> URL: https://issues.apache.org/jira/browse/LOG4J2-1482
> Project: Log4j 2
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.6.2
> Reporter: Sumit Singhal
> Attachments: csv-with-line-seprator-1.csv,
> csv-with-line-seprator-2.csv, csv-without-line-separator-1.csv,
> csv-without-line-separator-2.csv
>
>
> The header and first record are coming in first line in case of
> CsvParameterLayout. This messes up the header for the first file as well as
> for the subsequent files. And if we use line separator as part of header, the
> first file seems ok but the first record in subsequent files comes out to be
> empty with only commas.
