Question : Memory Leak :Microsoft.SharePoint.SPRequestManager.GetContextRequest(SPRequestAuthenticationModeauthenticationMode)

In our uls logs , we are getting message :

Process : OWSTIMER.EXE (_x-_-_)
Thread ID : _x_-_-

Category : Performance
Event ID : n-_-
Level : Unexpected

Message :

An SPRequest object was not disposed before the end of this thread. To avoid wasting system resources, dispose of this object or its parent (such as an SPSite or SPWeb) as soon as you are done using it. Due to flags specified at object creation, this will not be freed until processed by garbage collection. Allocation Id: {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} This SPRequest was allocated at at Microsoft.SharePoint.Library.SPRequest..ctor() at Microsoft.SharePoint.SPGlobal.CreateSPRequestAndSetIdentity(SPSite site, String name, Boolean bNotGlobalAdminCode, String strUrl, Boolean bNotAddToContext, Byte[] UserToken, String userName, Boolean bIgnoreTokenTimeout, Boolean bAsAnonymous) at Microsoft.SharePoint.SPRequestManager.GetContextRequest(SPRequestAuthenticationMode authenticationMode) at Microsoft.SharePoint.Administration.SPGlobalAdmin.get_ServerLanguage() at Microsoft.SharePoint.Administration.SPSqmTimerJobDefinition.Execute(Guid targetInstanceId) at Microsoft.SharePoint.Administration.SPTimerJobInvokeInternal.Invoke(SPJobDefinition jd, Guid targetInstanceId, Boolean isTimerService, Int32& result) at Microsoft.SharePoint.Administration.SPTimerJobInvoke.Invoke(TimerJobExecuteData& data, Int32& result)



Please help us identify the root cause and resolution for this .
