2010 EventID: 15004 back pressure 4.3.1 insufficient resources Issue RRS feed

  • Question

  • - Current version: Exchange 2010

    - EventID: 15004

    The mails is sent in bulk (3,000 EA, 3.5MB per 1ea). 15004 error occurred

    The disk, memory, and CPU are stable.

    By the way, sending mail is still slow and sending about 3,000 messages, about 30 times per hour.

    I had sent and received the mail to external at first. I have chaned the option.

    <Add key = "EnableResourceMonitoring" value = "false" /> in the EdgeTransport.exe.config file.

    I am able to send/receive mails after I changed.

    But.....Still a lot of mail is being sent slowly, and the queue file is still growing at 25GB.

    What should I do?

  • Hi,

    Event ID 15004/15005 means that resource pressure increased from Previous Utilization Level to Current Utilization Level. For troubleshooting this issue, please view application log for other related error events. If you can't see other related error events, refer to the following document to increase log level.


    And is there 3rd party agent enabled on Exchange Server? Are there firewall or AV software scanning emails?
