When the redis connection limit is reached and causes a crash, the following solutions can be considered:

Change the configuration of Redis: Increase the maximum connection limit of Redis by modifying the configuration file, for example, by changing the maxclients parameter.
Optimize the client program: Check the client program to ensure that the usage of connection pools is reasonable and to avoid excessive connections being occupied simultaneously.
Monitoring and optimization: Use monitoring tools to keep an eye on Redis, promptly identifying situations where the connection numbers are maxed out, and then making necessary adjustments and optimizations.
Horizontal scaling: Consider adding more Redis nodes to offload connection pressure and achieve horizontal scaling.
Load balancing: Utilize load balancing technology to distribute requests to multiple redis nodes, preventing overload on a single node.
Recovering from a crash: Promptly restart the Redis service after a crash, and check and restore data to ensure the system runs smoothly.

By following the above methods, the issue of Redis crashing due to reaching maximum connection can be effectively resolved. It is also recommended to regularly monitor and optimize the Redis service to ensure system stability and performance.
