OK I have done a filesystem search and found these:
Are those to worry about?
Also, this doesnt answer why everything stops working because Horde
has troubles communicating with the outside (some google domain or
whatever). Why does Kronolith stops responding? Why Turba stops
responding? Only IMP uses Gmail as the backend server for emails, all
other data is stored locally.
