While not an expert in tabs, I would appear to be a problem with the map/map fragment.
Are you including the map more than once across all the tabs?
I would try making sure the id of any added fragments (and map fragments) is unique.
You might also find it useful to remove any fragments that you are not using so as to lessen the chance for conflicts. This is likely to be something similar to removing the fragments that inside the tabs that aren't currently displayed. But like I said, I'm not an expert on tabs.
