我有一个使用spring-data-redis的后端进程 . 与retwis clone类似，它使用StringRedisTemplate . 在我的Digital Ocean液滴运行约3-4小时后，它神秘地停止了持久的新键 . 我的日志表明我的redis持久性代码正在被调用，它在spring-data-redis / jedis层以某种方式停止工作，没有任何错误迹象 .

Troubleshooting done so far

  • 我有足够的公羊 . Redis只用了6mb .

  • 我重新启动了我的后端进程，一切都按预期工作，正在插入键值 .

  • 我检查了redis-server.log . 这与我的spring-data-redis / jedis失败的假设是一致的 . 条目在插入我的最后一个密钥的同时停止 . 2015年9月8日的条目是它神秘失败的时候 . 第二天，08/10/2015的条目是我重新启动它 .

  • 我自己的应用程序日志没有显示异常 . spring-data-redis和jedis都没有 Logger . 所以他们不会抛出异常（因为我没有捕获任何异常）并且它们没有日志输出 . 显然，请求是spring-data-redis，spring-data-redis返回我的代码，没有例外 .

Next steps on troubleshooting?

spring-data-redis及其底层redis驱动程序“Jedis”中的日志记录量非常少 . 我已经确实登录了2，如果问题再次发生，将会看到是否有帮助 .

我也考虑过调试这个，但我认为此时只想切换到不同的驱动程序/项目 .
