Ralph Goers commented on LOG4J2-1405:
-------------------------------------

Yes, that is definitely the problem. If the file exists then RollingFileManager 
is created with the writeHeader flag set to false as a log file should never 
have more than one header. But since the file didn't roll over more log events 
are just going to be appended to the file.

However, we will need to check if the footer will be written again when 
OnStartupTriggeringPolicy runs.

> Hello,
> Updated 2.3 to 2.6. When reload tomcat7, the logfile (html format) not shown 
> correctly:
> {code}
> <tr>
> <td>13942164</td>
> <td title="http-bio-.....exec-49 thread">http-bio-.....</td>
> <td title="Level">INFO</td>
> <td title=" logger">ActionClass</td>
> <td title="Message">......</td>
> </tr>
> </table>
> <br>
> </body></html>
> <tr>
> <td>13936096</td>
> <td title=".....c-50 thread">http-bio.....50</td>
> <td title="Level"><font color="#993300"><strong>WARN</strong></font></td>
> <td title="logger">.....</td>
> <td title="Message">.... </td>
> </tr>
> {code}
> "</table><br></body></html>" is added in the middle, so html file cannot be 
> printed correctly.
> Can someone help how to fix this please?
> Here is log4j2.xml config:
> {code}
>  <RollingFile name="debug_html"
>                   fileName="@log4j.debug.html@"
>                   filePattern="@log4j.debug.html@-%i.html">
>         <HTMLLayout charset="UTF-8" title="....." />
>         <Policies>
>            <SizeBasedTriggeringPolicy size="5 MB" />
>         </Policies>
>      </RollingFile>
>   <Logger name="action" level="info" additivity="false">
