Exchange - Insufficient system resources RRS feed

  • Question

  • Hello,

     

    our customers keep failing over and back to their exchange server.  I talked with the failover company and she reported these errors to us )

    rsp: 452 4.3.1 Insufficient system resources and eturn-path rejected, got:452 4.3.1 Insufficient

     Currently the C:\ drive where Exchange is located only has 3.5 gb's left.  Is there any way we can resize the C drive without screwing anything up?

  • It would appear that you're experiencing Exchange 2007 Back Pressure.  It also appears that you only have Exchange 2007 RTM installed.  SP1 decreased the required disk space from 4GB to 500 MB.  So, upgrading to Exchange 2007 SP1 on the SBS server would seem to be a temporary workaround.  Ultimately, you should move the Exchange database(s) to a different drive with sufficient space for growth.

    ------------------------------------------------
    When the back pressure limits for hard disk drive space utilization are set to their default levels, the hard disk drive that stores the message queue database on an Edge Transport server or Hub Transport server must always have a fixed amount of free hard disk drive space. In Exchange 2007 RTM, the amount of required free hard disk drive space is 4 GB. In Exchange 2007 SP1, the amount of required free hard disk drive space is 500 MB. If the available free space is less than the required amount of free hard disk drive space, the hard disk drive utilization level is considered high. Therefore, all message flow stops. In that case, you must follow one of these steps:
    - Relocate the message queue database to a different hard disk drive that has more free space. For more information, see How to Change the Location of the Queue Database.
    - Increase the values of the PercentageDatabaseDiskSpaceUsedHighThreshold, PercentageDatabaseDiskSpaceUsedMediumThreshold, or PercentageDatabaseDiskSpaceUsedNormalThreshold parameters.
