   * What was the outcome of this action?
     catalina.out was copied to catalina.out.1 but catalina.out was not truncated.

In Ubuntu, the attached patch was applied to achieve the following:

The patch causes rsyslogd to write the file as syslog:adm and logrotated to rotate the file as syslog.
Without the patch, logrotated is not able to rotate file owned by syslog which is created by rsyslogd


  * Fix logrotated not able to truncate cataline.out (LP: #1964881)


Thanks for considering the patch.
