I am having issues with high memory usage by phdserver.exe. I cold start the server and within 3 days I am using over 8 GB which is my maximum physical memory. This can cause my server to lock up if I don’t catch it in time. What could be causing this?
There could be many reasons. One reason could be from poorly installed PHD applications or PHD applications that have been installed and are running but not being used. Another reason could be caused by the PHD user not having sufficient rights to the folder that contains the PHD archives. Many other reasons exist. I would also make sure PHD is patched and is a compatible version for your DCS if it is using non-OPC RDIs
