Alerts:

The case application tried and failed 3 times to successfully complete an update. This may be due to a network configuration issue or temporary outage.

This could be a result of several issues (locally to the ESA or network etc). 

From the CLI of the affected ESA, run "updatenow force". Wait for at-least 20 mins and verify if the alerts stop. If they dont stop I would recommend contacting TAC for assistance.

case application refers to AntiSpam. could be due to connectivity issue with update server.
I recommend to check case status in CLI by following commands: antispam status  or  'enginestatus all' also to check status of all engines.

if it is out of date, try - antispamupdate force ; or ; updatenow force.
then check antispam status again by above commands.

for further tshoot, you can check 'updater_logs' log in ESA's CLI: tail updater_logs
