SMTP error - Unable to read data from the transport connection.

Question

I believe there is some limit that is being exceeded (Timeout=100000). Do we know if these emails are being sent asynchronously?

Customer is trying to email a large volume of smtp email messages, we get an error, but in smaller groups of emails around 100-125 they are processed without error. Would you know what would be causing this?

Hi Lee,What is the recommendation for the spread?The scheduled process, request_billing_email.xml, runs (attached). This uses a hierarchy select to determine which invoice records to update. It then updates user_def5, user_def6, and user_def7 on the invoice record.This triggers the business rule, sces_invoice_delivery_xml. Rule condition 1, is then triggered which runs the custom xml that I’ve attached to the case, sces_invoice_delivery_xml.xml. This does a hierarchy select, then a perform_send_notificatoin, followed by an update_invoice to set user_def3 to Y, which indicates that that record has been sent.

Hi @andeus,I have seen it before that the email notifications can start getting out of sync with itself when the notification is triggered for large numbers all in one go.The solutions previously that I have seen have been to put a wait in the setup to space these out and make sure that the full amount does not back up in the system.Kind regards,Lee Pinchbeck
