Wed Jun 8 21:23:10 [conn665] Uncaught std::exception: boost::filesystem::create_directory: No space left on device: "/var/lib/mongodb/_tmp/esort.1307586190.1030033087", terminating
Wed Jun 8 21:23:10 dbexit:

In the above case it looks like the failure occurs when we try to generate an external sort directory in extsort.cpp, but there are other cases that can be problematic. It looks like we are calling dbexit such cases because a boost exception is not an expected mongo exception.

In another example, there may also be an issue when running out of space writing to the external sort files SERVER-3430:
