Getting error when initializing Membership.Provider for the first time after restarting the application

Question

We use MS Commerce Server Microsoft.CommerceServer.Runtime.Profiles.UpmMembershipProvider, and sometimes, when it starts for the first time after restarting the application, we get this error:

System.Configuration.ConfigurationErrorsException - System.Web, Object reference not set to an instance of an object. (C:\Inetpub\web.config line 425)
   at System.Web.Security.Membership.Initialize()
   at System.Web.Security.Membership.get_Provider()
   ...

Line 425 - Membership Provider Specification:

<membership defaultProvider="UpmMembershipProvider">
  <providers>
    <clear />
    <add name="UpmMembershipProvider"
      applicationName="app"
      enablePasswordRetrieval="false"
      enablePasswordReset="true"
      logonNameProperty="GeneralInfo.logon_name"
      requiresQuestionAndAnswer="true"
      requiresUniqueEmail="true"
      enableCreateDate="true"
      enableEmailAddress="true"
      enableLastLoginDate="true"
      profileDefinition="UserObject"
      passwordFormat="Hashed"
      maxInvalidPasswordAttempts="5"
      passwordAttemptWindow="1"
      type="Microsoft.CommerceServer.Runtime.Profiles.UpmMembershipProvider" />
  </providers>
</membership>

We took a memory dump, and this is what we got:

Has anyone come across something like this before? This does not happen every time the application restarts, and it seems that it is not located on one specific server (the site runs on several servers with a load balancer).

Answer 4

, web.config

type="Microsoft.CommerceServer.Runtime.Profiles.UpmMembershipProvider"

should follow the agreement specified in the documentation for System.Type.GetType(string typeName), that is, do not need to include the assembly and, possibly, the version number and all this jazz? Like at least something like:

type="Microsoft.CommerceServer.Runtime.Profiles.UpmMembershipProvider, Microsoft.FancyCommerceServerAssembly"

or even

type="Microsoft.CommerceServer.Runtime.Profiles.UpmMembershipProvider, Microsoft.FancyCommerceServerAssembly, Version=6.6.6.0, Culture=neutral, PublicKeyToken=..."
