Process exited with code 10 (0xa)
From BOINC Wiki
Process exited with code 10 means that the science application could not resume from a previously written checkpoint.
Most of these errors can be attributed to a broken drive sector or even a broken filesystem (e.g. some of these returned a checkpoint file point with what looked like a portion of the client_state.xml).
Best ask for help about this on the project forums.
