The error 'memcached error 10' is usually caused when the Memcached server has reached its maximum memory allocation limit. When this happens, Memcached can no longer store any additional data sent to it by the client and returns the error code 10. The error may also occur if the server is experiencing network connectivity issues, which prevent it from processing client requests.
To resolve the 'memcached error 10' issue, you can try one or more of the following solutions:
Increase Memory Allocation: You can increase the amount of memory allocated to the Memcached server to allow it to store more data. This can be done in the configuration file or by using the '-m' option when starting the daemon.
Monitor Memory Usage: You can monitor the memory usage of the Memcached server to ensure that it doesn't reach its limit. This can be done using various tools such as 'stats', 'top', or a custom monitoring script.
Check Network Connectivity: If the error is caused by network connectivity issues, you can check the network settings on both the client and server sides to ensure that they are properly configured. You can also try restarting the Memcached server or restarting the network services on the server machine.
Use Multiple Servers: If the above solutions do not work, you can try using multiple Memcached servers to distribute the load and reduce the chances of reaching the memory limit on any single server. This can be done using a load balancer or by manually distributing the workload among multiple servers.
