High Memory Usage

Certified Senior Developer
we have a send and a receive message node at two different process model.
Process flow is working fine i.e 1st PM is sending the message and 2nd PM is receiving the message, but in the system logs we find this exception which is attached below.

    This error indicates a process to process message couldn't be delivered because the execution engines were too busy but the action will be retried.
    You can verify if this is load-related by looking at the CPU usage and the perflogs folder.

    When you reproduce the issue, can you try pausing the process and see if that allows you to monitor it?

    If you can't pause it from the user interface use the Process Management Services plug-in available for download here in Appian Forum under the "Shared Components" record (forum.appian.com/.../all)- Smart Services and it's Pause Process smart service.

    This will let us know if the issue is the process is falling into an infinite loop locking up the engines.

    Hope this helps !
