Anyone seen this error before?

Anyone seen this error before?  This is a new one on me and just started on Monday.  It happens when you try to expand/open a data source, same as you would get if the login or password were wrong or you didn't have access.  It doesn't do it on all of them only some and seems to be very random.  I can edit the data source but can not save it.

InformationModelException at Spotfire.Dxp.Data:
Failed to initialize connection pool: Network error IOException: No buffer space available (maximum connections reached?): connect (HRESULT: 80131500)

Stack Trace:
