New Contents: Though function write() executed successful, the return value wasn't equal to the supposed write size. So, p_write_error() ran and the following message appeared: "Cannot write data to system activity file: Success". In this updated package, the sadc utility successfully writes the remaining input, thus resolving this issue.
