    100% CPU usage whenever doing anything



      100% CPU usage whenever doing anything


      FileMaker Pro



      Operating system version

      Windows XP SP3

      Description of the issue

      I am trying to help a customer to find out why tailored FilemakerPro application is causing 100% cpu usage when displaying various pages.

      I'm not involved with the actual development of the application; but i ran SysInternals ProcExp to see if i could get some more information.

      From what i can see (please see the attached screenshot); theres a thread executing a function called "Draco::BufferSwapIStream" that consumes all CPU.

      Anyone have a clue what might cause this CPU hogging ?


      Use another computer.

          Thanks for posting!

          To clarify, this only occurs when running this one particular solution and only on this computer, correct?

          Just to rule out the basics, let's try uninstalling and reinstalling FileMaker Pro 9. If you continue to see this issue, create a new administrator user account and attempt to reproduce the issue there.
