使用python脚本写入redis抛出磁盘已满异常，scrapy却没有抛出异常。

Question

同时使用python脚本和scrapy-redis向同一个redis写入数据，脚本报错：redis.exceptions.ResponseError: MISCONF Redis is configured to save RDB snapshots, but it is currently not able to persist on disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.

查看之后是磁盘满了，但是scrapy-redis却没有报错，是为什么呢？
