Today when I tried to save a list item I got:
The server was unable to save the form at this time. Please try again.
This worked last night when I shut down my laptop and put my SharePoint VM to sleep.
When I paused my farm trouble started and SharePoint seems to be struggling with this. I guess this isn’t an expected situation. I did an IISreset and everything started to work again.
I guess that I should shut down my SharePoint farm at the end of the day.
