This is a warning message, rather than an error message, and thus there is no need for alarm. FIMS is just telling you that it is using more memory than allotted for in its settings.
Resolving this message is also fairly easy:
  1. Close FIMS.
  2. Open the Folder N:\found\configfiles.
  3. Richt click on the file called and open with Notepad. 
  4. Add line that says "-mmax 8192". The number here is a good example, but you need to enter a number that is larger than what the warning message said. 
  5. Log back into FIMS and you should be good to go!
