Linux环境下的Redis管道崩溃
Linux环境下的Redis管道崩溃

我正在使用带有Python的芹菜库来并行处理一些相当大的数据集。但是我每天运行的任务，每两到三天中断一次，造成以下错误。
CRITICAL/MainProcess] Unrecoverable error: 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.',)红宝石原木看起来像

7633:M 12 Apr 08:01:35.188 * Background saving terminated with success相关的系统配置如下
- Python 3.6
- 芹菜4.2.1
- Redis Server和CLI 4.0.9
- Ubuntu 18.04 (仿生)
有趣的是，完全相同的配置和系统在另一个(开发)服务器上运行良好，另外一个运行Ubuntu16.04。但生产失败了。请注意，我不是芹菜和红葡萄酒方面的专家，只是在谷歌和一些教程之后，代码才开始工作。因此，请尽量将故障排除步骤保持在相对基本的条件下。另外，当我在shell上ping redis-cli时，我得到一个pong作为回报，这意味着服务器正在运行。
