Troubleshoot issues with Microsoft SharePoint Foundation.

FYI : When I am comment out the all membership and rolemanager tags from the central Administration site web.config then it working fine i think the problem in some where in the membership provider tags.

Please help me out this problem Thanks

I think that the 3 web config will need to be configured differently eg

This for your FBA Site

<membership defaultProvider="i">
  <providers>
    <add name="i" type="Microsoft.SharePoint.Administration.Claims.SPClaimsAuthMembershipProvider, Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />
    <add name="CustomFBAMembership" type="CustomMemberShipProvider.Class.CustomMemberShip,CustomMemberShipProvider,  Version=1.0.0.0, Culture=neutral, PublicKeyToken=99f33d5f328d7f5a"/>
  </providers>
</membership>
<roleManager defaultProvider="c" enabled="true" cacheRolesInCookie="false">
  <providers>
    <add name="c" type="Microsoft.SharePoint.Administration.Claims.SPClaimsAuthRoleProvider, Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />
    <add name="CustomFBARole" type="CustomMemberShipProvider.Class.CustomRoleBase, CustomMemberShipProvider,  Version=1.0.0.0, Culture=neutral, PublicKeyToken=99f33d5f328d7f5a"/>
  </providers>
</roleManager> 

This for the token and central admin

    <membership defaultProvider="i">
  <providers>
    <add name="CustomFBAMembership" type="CustomMemberShipProvider.Class.CustomMemberShip,CustomMemberShipProvider,  Version=1.0.0.0, Culture=neutral, PublicKeyToken=99f33d5f328d7f5a"/>
  </providers>
</membership>
<roleManager>
  <providers>
    <add name="CustomFBARole" type="CustomMemberShipProvider.Class.CustomRoleBase, CustomMemberShipProvider,  Version=1.0.0.0, Culture=neutral, PublicKeyToken=99f33d5f328d7f5a"/>
  </providers>
</roleManager>

Try to debug your code. It is likely in issue with your custom membership provider, since it works when you remove it from the web.config. When it is added to the web.config your membership provider is initialised. Also check the ULS log for a stack trace, which likely will pin down your problem.
