The Co-Pilot software detects if your virtual machine is in an unrecoverable state (due to unexpected errors, lost of connectivity, etc.), and reboots/resets it to start the execution of new experiments again. This will not affect at all your work unit or BOINC credit. However, it should only happen very rarely - if it is frequent you almost certainly have a network connectivity problem.
