error 452 4.3.1 no exchange mail being sent RRS feed

  • Question

  • All of my mail came to a halt in the middle of the night.  I tried telnet the domain but I get the error  452 4.3.1 insufficient system resources.  I have read that my queue volume needs to be under 4gb, but there are very few messages in the queue viewer. 

    Any help is appreciated,

    check diskspace on the drive where exchange is isntalled

    if it drop below 4 Gb the transport service stops.

     

    free up space and restart the transpoert service.

  • Hello Anonymous9561645,

    •    Cause - Due to 4.3.1 Insufficient system resources (Back Pressure issue) No sufficient disk space
    •    Resolution
    After creating the sufficient disk space on Drive where mail.queue folder is located, your issue will be resolved

    If you think there is sufficient disk space then it stop the Transport service and rename the Queue folder (mail.queue) and then restart the Transport service.

    And if need then also add the extra Memory on the server.

  • Hi,

    To resolve this problem, please free disk space on the drive that store the message queue database and logs.

  • Hello.

    Yesterday I found in log files of my Exchange 2013 some errors and lost some very important messages in summary. I can't resolve this problem with free disk space, because on disk with queue db 900Gb free space! Size of mailbox database is around 230Gb

    Interesting, that in logs last 2 weeks errors was found from 26 to 28 of February. Before and after this time no errors.

    Exchange installed with all last cumulative updates.

    Anybody have ideas, why it's happened?!

    I'm afraid that can happened in future and I will not know about this!

    Part of log with errors.

    Recipient OK,
