why does WFE server take 95% of RAM in Project server 2010 RRS feed

  • Question

  • Hi everyone,

    I have lunched a project server 2010 in a farm with 3 servers: application server, WFE and Report server

    application server: 8G RAM

    WFE:8G RAM

    report server:8G RAM

    I have no idea why WFE take more than 95% of RAM while there are just 3 project server-related processes:

    w3wp.exe = 491M

    w3wp.exe=212M

    owstimer.exe=330M

    what should I do?

  • 8 GB is the MINIMUM amount of memory a SharePoint server should have. That you're using 95% isn't necessarily surprising.

    Is this a Hyper-V VM using dynamic memory?

    Where are the search service components running? Are there any crawls in progress?

    Where is SQL Server running? Another server you haven't listed?

    Task Manager should list all the processes. You can sort by memory and you should see where it's going.

    Alternatively you can set up a performance monitor log to determine which processes are taking the most memory.

  • Hi,

    I would check which other processes are using the memory as the processes you mentioned are consuming only ~1.2Gb of the available memory.

    Also, if you are using virtualization for your environment I would also check how the host is performing and the VM memory configuration

    Hope this helps

  • Look at what services are running on each WFE.  Go to SharePoint Central and look at Manage Servers in Farm"  and compare the services running on each.

    hi,

    I stopped IIS and there was no w3wp.exe process and saw 80% of RAM is occupied.

    I think windows server 2008 R2 is consuming all the RAM. if a windows server 2008 R2 on a VM is configured correctly, what will be the amount of  occupied RAM?

  • Hi,

    If you check the Task Manager, can you see which processes are consuming the memory? You may need to display processes from all users in order to display all processes

    If no processes are consuming the VM memory but you still see the RAM heavily used I would check:

    - if you have Hyper-V/VMWare enabled on the VM where you are running another VM (I've done that once)

    - VM memory configuration (if memory ballooning has been enabled and maybe you do not have enough memory on host?)
