From the SFN article;mr_mark":2mtt5kg9 said:I saw that too. I was wondering about that. Wonder if it's hardware or software. If it's software they can correct that easily. If it's hardware it may have been a fluke and the next thruster will work correctly.
"The roll on the second stage was also a non-fatal situation. We think the actuator may have overheated due to radiative heating from the nozzle," Musk said. "This is speculative, but we can trace the problem down to the roll actuator itself."
More insulation will be added around the actuator to prevent the same problem on the next launch.
