Toyota suffered a major production setback last month when it had to shut down all 28 vehicle assembly lines at all 14 of its automotive plants in Japan. The company is now saying that this bad memory was caused by a lack of memory.

According to the Guardian, Toyota said the August 29 production stoppage occurred after “insufficient disk space” caused a system malfunction following a standard maintenance procedure. In a statement, the automaker said “data that had accumulated in the database was deleted and organized, and an error occurred due to insufficient disk space, causing the system to stop.” The data was transferred to a different server with more capacity, allowing production to start back up the next day.
