Sharepoint - "The server was unable to save the form at this time. Please try again", when adding new announcement
I have found this to be directly related to the Search Host Controller Service. This apparently is gobbling up all the memory on the WFE. Once restarted I can now save the form items. I watched it regress from 8gb (max on this server) to about 6.7gb and suddenly this red error went away. I plan on doubling the memory to 16gb to try to remove the problem altogether.
