Allocated Memory Alert on ServerName RRS feed

  • Question

  • Hi,

    I have an SBS 2003 Premium installation that is driving nuts with the "Allocated Memory Alert" emails from SBS Monitoring. Here's some details:

    Environment:

    1) Microsoft Windows Server 2003 for Small Business Server Service Pack 2. Hardware is dual Intel Xeon 3.2GHz with 3.75GB Ram.

    2) Service Pack 1 for SBS 2003.

    3) Boot.ini: multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Windows Server 2003 for Small Business Server" /fastdetect /3GB /Userva=3030 /NoExecute=OptOut

    4) Exchange: Version 6.5 (Build 7638.2 Service Pack 2).

    5) SQL: SQL Server Standard Edition, v8.00.2055 (SP4).

    6) ISA 2004 SP1.

    7) Antivirus is Trend's new Worry Free Business Security Advanced v7 (ie. WFBSA). Had the alerts even with v6. Not using "Smart Scan mode"which is the recommendation for SBS. That said, we all know that ScanMail for Exchange (ie. SMEX) likes memory, but light email usage (12 SBS users).

    8) Task Manager stats (don't forget OneNote 2007 & 2010 does OCR :-)
    Totals:

    Processes: 76
    CPU Usage: 2%
    Commit Charge: 4275M / 9834M

    Graphs: CPU Usage runs ~1-5%, usually under 2%. Page File Usage at 4.16GB.

    10) Performance Options = Let Windows choose what's best for my computer.

    11) Virtual Memory = Custom Size: C: = 2046/2046, D: = 4096/4096

    12) System is fully patched (unless I've missed somethingand processesusing theover aless criticalby usingMonitoring and over the years).

    Here's the usual email report, and then I'll mention what I've done to correct.

    "A large amount of memory is committed to applications and processes. Consistently high memory usage can cause performance problems.

    To determine which processes and applications are using the most memory, use Task Manager. Monitor the activity of these resources over a few days. If they continue to use a high level of memory and are less critical processes or services, try stopping and then restarting them.

    You can disable this alert or change its threshold by using the Change Alert Notifications task in the Server Management Monitoring and Reporting taskpad."

    Corrective actions tried:

    1) I've monitored Task Manager at the times of day when the alert usually fires, as well as reviewed Event Logs and don't see anything unusual.

    2) I've been bumping up the Allocated Memory Threshold for the last couple months (usually adding 250MB each time, which stops the alert for a week or so). It's now set all the way up to 4563402752 bytes (ie. 4.25GB), which is more than the 4GB physical memory installed.

    If this alert is something known to be problematic? Do others just disable the alert? I'd like to see the Allocated Memory alert work in case a real problem arises.

    Any ideas? You comments or suggestions will be greatly appreciated.

  • For comparison my SBS 2003 Premium with 4 GB RAM shows the Allocated Memory Counter Average is 4905884175 and my Threshold is 5507008525. Over the years I have also increased it several times, but I'm not too worried if the alert occasionally fires.

  • Been tweaking the boot.ini lines.

    Have a look at and try removing the /3gb and userva portions.

  • nodding in Kev's direction but also pointing out that if you _really_ want the lowdown on why this is so:

    takes a bit of reading to get there though.
