The task is running 6 times as I log an error message with log4j2 each
time spring triggers the task
2015-07-02 06:00:00,280 ERROR [pool-4-thread-1] service.PatientDaoService

You can see the task is triggered several times at the same time.
Here’s the relevant part of my spring config
<bean id="springCronTask" class="SpringCronTask">
<property name="patientService">
<ref bean="patientService"/>
</property>
<property name="localisedTextService">
<ref bean="localisedTextService"/>
</property>
</bean>
<task:scheduled-tasks>
<task:scheduled ref="springCronTask" method="sendReminders" cron="0 0 6
*
* ?" />
</task:scheduled-tasks>

Agreed and we are running Apache Tomcat/7.0.52 (Ubuntu) I figure Ubuntu
are pretty good at pushing out updates and I’m not too concerned if we’re
a little behind in releases.
Also, I don’t think it is a Tomcat issue but something in the our
configuration of either tomcat or spring.

The only file here is manager.xml

A ROOT directory with a simple redirect jsp for redirect purposes
