In my application I have used Send Email Smart Service to send Emails to users but for some random requests that node is breaking and mail is not being sent to the users and If the node is restarted then it proceeds ahead without any error in Monitoring mode.
SMTP server configurations also looks fine in custom.properties file.
I have gone through the Server logs and below is the error for one of the such stuck request.

Not sure why it is happening randomly. Please find the complete server log for this error in attachment.
Any suggestion is appreciated!!

I would double check firewalls/SMTP Server whitelist to see if maybe only a partial list of your app servers are permitted to send emails. Perhaps when you restart, it tries on a different app server and is able to succeed. Try and check SMTP server logs for other clues
