Starting application pool concurrently causes erro

Question

I have a powershell script which can run asynchorusly to start multiple application pools.

But when i have a certain amount of app pools to start it throws the following error:

The running command stopped because the preference variable "ErrorActionPreference" or common parameter is set to Stop: [ServerX] Connecting to remote server XXX failed with the following error message : The WS-Management service cannot process the request. This user has exceeded the maximum number of concurrent shells allowed for this plugin. Close at least one open shell or raise the plugin quota for this user. For more information, see the about_Remote_Troubleshooting Help topic.

The maximum shells per user is 10000.

It seems that there is more happening beneath the hood when appcmd runs but not sure how i can get around this issue

Any advice would be great

Below is the winrs config
