I have a client that is having issues with the FileMaker program installed on their server. The info I got from their IT support is that about once a week they have one or more processes get completely out of control and will utilize between 50 and 100% of the available CPU.
Today the process was fmshelper.exe and it handily sucked back 50% of the CPU all day long until they they terminated it at (with no visible ill-effects). Apparently, the server is now idling at 1% CPU or less and the process hasn't returned.
Not sure of the server version.
