SharePoint 2013 Preview – Hungry search service

  • 项目

Due to the many response I get: This post was written specifically for the Preview of SharePoint 2013
The memory leak is resolved in RTM. Please do not apply the memory settings in production!

 

Just today there was some discussion on our internal DLs about the noderunner.exe processes of the Enterprise Search service being very hungry for CPU and RAM.

It turns out that there is a memory leak and a lot of debug code involved [REMEMBER: We are still at beta here J].

Jose Vigenor from MS beta support pointed to two options to contain these processes:

  1. Use Set-SPEnterpriseSearchService -PerformanceLevel Reduced to reduce the CPU impact the search service has on your test environment.
  2. Modify the C:\Program Files\Microsoft Office Servers\15.0\Search\Runtime\1.0\noderunner.exe.config so that it can only consume X amount of RAM.
    Change the value at <nodeRunnerSettings memoryLimitMegabytes="0" /> to any amount of RAM you like to contain the memory leak.

Good luck!

    Thanks for the tip, it's proved very handy to control the process on my dev machine. I did however hit a problem with the memoryLimitMegabytes when I was changing the search topology in PowerShell. Once I had cloned the topology, changed things around and then went to reactivate the topology, the script took about 10 minuts before it finally crashed out with the error "Failed to connect to System Manager" Unable to connect to system client with derived management URIs. Exception: Failed to connect to system manager. SystemManagerLocations: net.tcp://win2k8sp15/78580D/AdminComponent1/Management    at Microsoft.Office.Server.Search.Administration.SearchServiceApplication.GetSystemClient(IList`1 systemManagerLocations)     at Microsoft.Office.Server.Search.Administration.Topology.ApplicationAdminLayer.Reconnect() c80fcf9b-cf6b-2083-a27f-5d57c7dc4ef3 Deeper analysis of the ULS logs shows that the DBConnector created by the Noderunner process threw an OutofMemory exception. Removing the Noderunner.Exe.Config memory restriction and rebooting the server allowed me to submit the topology change. Paul.

    Is This <nodeRunnerSettings memoryLimitMegabytes="0" /> Bytes or KiloBytes or MegaBytes ? Thanks Nigel

    we have the same issue, rebooting the server works for a wile, right now the server already has 16 GB of memory but it just keeps eating more and more.
