I saw similar issues reported a year ago (https://forums.activiti.org/content/repeat-timers-issue-activiti-5170). The jobExecutor is true in my case . Here is my processengine configuration
<code>
<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
<property name="dataSource" ref="dataSource" />
<!– <property name="transactionManager" ref="transactionManager" /> –>
<property name="databaseSchemaUpdate" value="true" />
<property name="deploymentResources" value="classpath*rocesses/*.bpmn" />
<property name="jobExecutorActivate" value="true" />
<property name="mailServerPort" value="1025"/>
<property name="beans">
   <map>


    <entry key="analytics" value-ref="taNotificationManager" />
    <entry key="analytics1" value="taEmailNotification" />
   </map>

</property>

</code>

When I remove the intermediate time the process loops fine, so the issue is with the timer. I did see lot of users complaining about this. For now I went with a very crude way of implementing using service task and java sleep timer

Resolved it using the following proteries to the engine configuration.
<code>
<property name="jobExecutorActivate" value="true" />

<property name="asyncExecutorActivate" value="true" />

      <property name="asyncExecutor" ref="asyncExecutor" />

<bean id="asyncExecutor" class="org.activiti.engine.impl.asyncexecutor.DefaultAsyncJobExecutor">
    <property name="defaultAsyncJobAcquireWaitTimeInMillis" value="1000" />
    <property name="defaultTimerJobAcquireWaitTimeInMillis" value="1000" />
</bean>

      </code>

Do keep in mind that this will poll your database every second. That's more load than the default (10 seconds).
