+=====HeapLowGrails=====
+**Level:** __Critical__ FIXME
+**Purpose:** Identify when one of the Errigal Grails Application is using an excessive amount of heap memory for a defined duration of time.
+**Scenario:** ReportingManager on EXTApps2 used more than 90% of its Heap for 120s. Typical reason in this instance would be a rogue report run with very broad input variable e.g a trap report specifying range of over year.
+**Resolution:** Monitor to see if heap usage is reducing. If not and it becomes evident that the application will run out of memory, perform a restart of the application.
+**Manual Action Steps:**
+\\
+Script Based Restart
+<code>
+cd /var/tomcat/ReportingManager/bin/
+./shutdown.sh
+ps aux | grep -i Reporting
+(Kill process if still running: kill $pid)
+./startup.sh
+</code>
+Ansible Based Restart
+<code>
+ansible-playbook -i ../env-configuration/${env}/hosts.ini --diff --vault-id @prompt reportingmanager.yml -e "actions='stop,start'" --limit $appHandler
+</code>
+**Auto Clear:** Yes
