PI OleDb Enterprise: Communication link failure

I'm currently facing an issue with a linked server where the PI OleDb Enterprise is used to connect from MS-SQL to AF. From time to time, we are getting the following error message


The PI OleDB Enterprise and MS-SQL server are running on a different machine than the AF server. The PI System explorer on the SQL server machine is working, so the AF service is up and running.

The same error is written to the AF logs on the AF server, as shown below


I have already tried to restart the PI OleDb Enterprise service, but it does not solve the problem. Note that this message appears from time to time.


Does anyone know what the reason could be and how it could be solved?
