Tomcat8 on Ubuntu .log.gz already exists not overw

Question

On our Tomcat servers I regularly see warnings like below:

/etc/cron.daily/tomcat8:
gzip: /var/log/tomcat8/app1/app1.log.gz already exists; not overwritten
gzip: /var/log/tomcat8/app2/app2.log.gz already exists; not overwritten
gzip: /var/log/tomcat8/app3/app3.log.gz already exists; not overwritten
gzip: /var/log/tomcat8/app4/app4.log.gz already exists; not overwritten

I found a similar issue as discussed in Tomcat7 logrotate: superx_default_xml.log.gz already exists however an answer was never provided.

Although search for an answer I can't seem to find a solution for this problem and was hoping if someone here could point me in the right directlion.

We are running our Tomcat 8 servers on Tomcat8 servers on Ubuntu 16.04.1 LTS.

Kind Regards.

- find /var/log/$NAME/ -name \*.$LOGEXT -daystart -mtime +0 -print0 \ + find /var/log/$NAME/ -name \*[0-9].$LOGEXT -daystart -mtime +0 -print0 \

log4j adds date suffix to log files names on rotation, so there must be a digit there so just add this digit to glob in /etc/cron.daily/tomcat8
