insufficient memory to continue the execution of the program

While clicking on the 'Search settings' page, you get the following error:
'insufficient memory to continue the execution of the program'
Fix:

1. Perform the below steps on every WFE in the farm:
   net stop WSSTimerV3
   net start WSSTimerV3
   
2. If you are not through the first step, kill the MS Search.exe on each WFE
   Task Manager -> Processes -> MSSearch.exe -> right click -> end the process
   (If you cant see the process in the list, check the 'show processes from all users')
3. Try flushing the local mso config cache to avoid this error throwing often.
