The WBEM Server limits have been exceeded?

rhopkins76 · February 18, 2015, 4:05am

I’ve setup a pull server and have two clients getting configs from it. Features got installed and files downloaded, so things work, but when I try and look at the config on the server, I’m getting this error:

PS C:> Get-DscConfiguration
Get-DscConfiguration : The WBEM Server limits have been exceeded (e.g. memory, connections, …).
At line:1 char:1

  + FullyQualifiedErrorId : MI RESULT 27,Get-DscConfiguration

Anyone run across this one before?

To clarify - you’re getting this error on the pull server? I think someone reported this or something very similar to it; it was a bug in the xPSDscWebService resource’s Get-TargetResource function, I think. (Typing this from memory, I may have the resource name wrong. Whatever the one that we use to install a pull server is called.)

On the client servers actually. Pull server is working great. Pull server is 2012 R2, clients are both 2008 R2.

Ah, ok. Can you post a copy of the configuration that’s being applied to the clients, or does that contain sensitive information?

Were you getting this error before the configuration was applied, or only after they pulled their configs? If you push the configuration, do you get the same error?

rhopkins76 · February 18, 2015, 4:31am

I did push some configs to the client servers early in my testing and was able to run Get-DscConfiguration successfully then, its after the config was pulled that I started getting the error. Here is a cleaned up version of my script so far:

$ConfigurationData = @{
AllNodes = @(
@{NodeName = ‘EQDEVOPS1’;Role=@(‘DSCPullServer’)}
@{NodeName = ‘EQDEVOPS2’;Role=@(‘Web’,‘DevInt’)}
@{NodeName = ‘EQDEVOPS3’;Role=@(‘Web’,‘Alpha’)}
)
}

So on the two clients, you’re only using WindowsFeature and File resources? Nothing else?

rhopkins76 · February 18, 2015, 5:11am

Yes, for right now, I’ll be working in xWebConfiguration stuff soon and hoping it all works on 2008 R2.

system · February 18, 2015, 5:12am

Hmm… how many File and WindowsFeature resources are being applied to these servers? You had a “truncated” note in the code that you posted. Just wondering if it has to do with the volume of resources in the config, rather than a bug in a specific resource module.

rhopkins76 · February 18, 2015, 5:20am

I was just trying to cut down on the length of the post a bit, but went ahead and added everything in so you can see exactly what I’m doing.

rhopkins76 · February 18, 2015, 5:24am

I should say though that those two file resources have 37,018 Files and 5,397 Folders between them. Would that choke everything from reporting back? Looking in the event log I can see everything going well and ending in an “Consistency engine was run successfully.” event.

system · February 18, 2015, 5:28am

Unfortunately, there’s no way for me to know that without getting an answer directly from Microsoft. The File resource is a bit unique in that it’s implemented directly as a WMI class (possibly in native C or C++ code), rather than as a PowerShell script module or .NET assembly.

That does, however, give you plenty of things to try. You could tweak your config and comment out the File resources, see what happens, then add them back in one at a time. If a large folder causes the error, try pointing it at a test folder with only one file, or directly at a file, that sort of thing.

I’d also be curious to know what happens if you apply this same configuration to a Windows Server 2012 machine; does it get the same error?

rhopkins76 · February 18, 2015, 5:34am

Gunna have to build another 2012 R2 server to test on, unfortunately everything here is standardized on 2008 R2 still, but I’ll give it a shot. Thanks for the help!

rhopkins76 · February 18, 2015, 6:27am

Its the number of files that is causing the problem. The SubItems property returns a list of every file in the directory structure. Gunna have to deploy them as Archive or maybe Chocolatey packages or something.
