Config service reporting OutOfMemory exceptions

Article ID: 51884 - Last Review: May 20, 2015


Poor performance on the Enterprise Server.  When checking the Config Service log you find references to OutOfMemory exceptions. 


On busy sites the DeleteTracking table in SQL can grow quite large, and the Config service keeps some of it in memory after each Maintenance runs.


There are two steps to resolving this issue:

1. Setting the DeleteTracking cleanup interval in SQL.

  • Open SQL Management Studio.
  • Expand CCMData.
  • Expand Tables.
  • Find the dbo.tblEnterpriseConfig_Enterprise table.  Right-click and select Edit top 200 rows.
  • Scroll to the right and ensure that DeleteTrackingCleanupInDays is set to 1.
  • Close SQL Management Studio.


2. Modify the service configuration file.
  • Go to the [INSTALL DIRECTORY]\CCM\Services\MaintenanceAlarmDispatcher\ folder.
  • Open the MaintenanceTasks.config file in notepad.
  • By default it will look like the following:

  • You will need to comment out the <add key="DayOfMonth" value="1" /> entry by adding  <!-- to the beginning and --> to the end (see image below).
  • Modify the <!--<add key="DayOfWeek" ... entry so that it shows <add key="DayOfWeek" value="Everyday" /> (see image below).

3. Purge the content of the tblConfig_DeleteTracking table in SQL.

  • Launch SQL Studio Management.
  • Create a new query.
  • In the Query Editor, type in the following query;

  • Click on Execute.
  • Upon completion, the table will be clear of its content.

This will increase the frequency of the maintenance task to purge your DeleteTracking table and will now be purged on a daily basis on items older than 1 full day.
