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.
