Question

我已经看到有关此错误的各种问题，但找不到任何相关的解决方案。

我正在使用 stackexchange.redis.strongname 程序集版本 1.2.6.0 连接到 redis服务器版本3.2.10 ，并随机面对RedisConnectionException。我们的架构是基于AWS托管的Web场架构，有时一台机器无法连接到Redis服务器，但另一台机器运行良好。因此，这使我们确信Redis服务器已启动并且可以正常工作。此外，当一台计算机无法连接并且工作正常且没有任何问题时，我们也尝试使用redis-cli.exe进行连接。

我要分享以下完整的例外情况：

#if stored dictionary like strings
df['score']=df['score'].map(ast.literal_eval) 

df1 = pd.DataFrame(df.pop('score').values.tolist())
df1.columns = [f'score{i}' for i in range(1, len(df1.columns) + 1)]
df = df1.join(df)
print (df)
   score1  score2     pvpdate
0      29      24  2018-05-23
1      23      24  2018-05-29
2      36      25  2018-05-23

这是我用来创建与Redis服务器的连接的代码

[RedisConnectionException: It was not possible to connect to the redis server(s); ConnectTimeout]

    [RedisConnectionException: No connection is available to service this operation: EVAL; It was not possible to connect to the redis server(s); ConnectTimeout; IOCP: (Busy=0,Free=1000,Min=2,Max=1000), WORKER: (Busy=767,Free=32000,Min=2,Max=32767), Local-CPU: n/a]

任何人都可以帮助我找出此问题的根本原因，或者一些调试它的步骤也会有很大帮助。
