Reporting Services High Memory Utilization

  • Hi,

    Daily we are facing High memory utilization around 1 pm to 2 pm for reporting services. After restarting

    the Reporting Services the memory utilization becomes normal.

    Following are configuration details

    Windows OS : 2003R2-Enterprise Edition 64 bit SP2

    SQL Server 2005 Enterprise Edition 64bit SP4

    min and max memory settings for SQL Database Services are the default settings not changed

    min: 0

    Max: 2147483647

    RAM : 16 GB

    Reporting Service Memory setting details are as follows

    <Service>

    <IsSchedulingService>True</IsSchedulingService>

    <IsNotificationService>True</IsNotificationService>

    <IsEventService>True</IsEventService>

    <PollingInterval>10</PollingInterval>

    <WindowsServiceUseFileShareStorage>False</WindowsServiceUseFileShareStorage>

    <MemoryLimit>60</MemoryLimit>

    <RecycleTime>720</RecycleTime>

    <MaximumMemoryLimit>80</MaximumMemoryLimit>

    <MaxAppDomainUnloadTime>30</MaxAppDomainUnloadTime>

    Please let me know the best recommend memory settings for reporting services in above rsreportserver.config file.

    Any other way to keep reporting services memory utilization normal.

    Thanks and Regards,

  • Did you resolve this issue and how?

  • So, the first thing is that in this situation you absolutely want to set the Max Memory for the database engine, I can't recommend a value because I don't know enough about the server. Here is are some questions that need to be answered:

    1. Is the SQL Server just hosting SSRS and the Report Server databases or does it host other user databases?

    2. Please define "high memory usage" and problems that this is causing?

    3. Are there any jobs running during this time frame (index maintenance, data loads)?

    4 What is the main workload on the server, reporting, OLTP?

  • The values you have set are the defaults for SSRS in 2005.

    Those defaults are based on "available" memory which is not the same as free memory. If you have large reports that could require a lot of render time, you could be competing against SQL and against the OS.

    Since you have 16GB of memory on the server and you are running SSRS on the same box, I might start max memory in SQL at 8GB. This would leave memory for the OS as well as some memory for your reports. That said, it is just a starting point.

  • The ReportServer has very, very little processing to do. It is the other SQL database that is the work horse.

    So that is why I can't figure out why in Task Mananger ReportingServicesService.exe is using 667,440k memory use and sqlserve.exe is using 542.080k memory use.

    Tough to say not knowing your memory configuration.

    The ReportServer database will do very little work. But the executable for Reporting Services can do a fair amount of work because of the rendering, sorting, grouping etc that it must do.

  • It is Windows2008 server, SQL 2005.

    64gb of installed memory.

    SQL Server properties is AWE enabled.

    Minimum server memeory is 256mb

    Maximum server memory is 51200mb

  • Are you seeing performance issues?

  • No...

    I just could not explain why it was using so much of the memory when not doing any processing.
