Public bug reported:
We keep receiving cron messages from our tomcat machines:
/etc/cron.daily/tomcat7:
gzip: /var/log/tomcat7/lnhpd-catalina.2016-08-15.log.gz already exists; not
overwritten
And when looking at /var/log/tomcat7:
# ll /var/log/tomcat7/lnhpd-catalina.2016-08-15.*
-rw-r--r-- 1 tomcat7 tomcat7 143355 Aug 17 08:22
/var/log/tomcat7/lnhpd-catalina.2016-08-15.log
-rw-r--r-- 1 tomcat7 tomcat7 10605 Aug 15 23:56
/var/log/tomcat7/lnhpd-catalina.2016-08-15.log.gz
We notice the uncompressed file was created on Aug 17th despite what the
date embedded in the file name says. On Aug 17th, at 8:22, the tomcat7
service was manually restarted due to security update to OpenJDK-7. This
seems to have trigger the problematic behavior.
The first entry in the newly created is from the 17th:
# head -1 /var/log/tomcat7/lnhpd-catalina.2016-08-15.log
2016-08-17 00:11:40,179 [http-bio-8080-exec-8] INFO
ca.gc.hc.util.ApplicationGlobals- Initializing Localization to en_CA
And if we look at the last entry of the previous day:
# zcat /var/log/tomcat7/lnhpd-catalina.2016-08-16.log.gz | tail -1
2016-08-16 23:55:57,185 [http-bio-8080-exec-10] WARN
org.apache.struts.util.PropertyMessageResources- Resource
resources/ApplicationResources_fr_CA.properties Not Found.
So both files have consecutive log entries but the newly created file
has the wrong date embedded in its name.
Having tomcat reusing old dates for new files causes problem later on
when the cron job tries to compress old logs and trip on existing files.
This is what generates the cron emails.
