Send E-mail smart service breaks with "An error occurred in executing an activity class." However, when I restart the node, it works fine.

ashwing264 over 5 years ago

We have a wrapper process(Process A) which calls another process(Process B) as an MNI. This process B has a send e-mail smart service node. We have observed that this send e-mail smart service node breaks in about 25% of the cases and the alert simply says "An error occurred in executing an activity class."

However, when I go into the process and re-start the broken node without making any changes, then the node works fine. Has anyone else encountered this? What is the solution to avoid it?

Thank you!

Hi Ashwin,

Have you checked the logs to see if there's a more descriptive error message? That would be my first debugging step.

On several projects, I've seen a similar issue where there is a limit set on the mail server to start rejecting emails from a particular sender the volume exceeds a certain threshold. This is to protect against malicious email trojans. How many emails are being sent at once (how many loops does the MNI perform)?
