=====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
