CRM 2015 and SharePoint 2013 Integration Issue

Hi,

I am trying to install CRMListComponent sharepoint solution in SharePoint 2013 and keep getting this error:

The sandboxed code execution request was refused because the Sandboxed Code Host Service was too busy to handle the request. 

I have done all the recommendations from this link and still have the same issue.

Anyone has any idea?

OS: Windows 2012 R2

CRM: 2015 

SharePoint: SharePoint 2013 Standard edition

Everything is on my local VM.

Thanks.
