What's Causing This Error
The error message 'memcached unable to locate node' indicates that the Memcached client is unable to connect to the specified server node. This error can be caused by a few different reasons such as:
- The Memcached server may not be running or may have crashed.
- There could be a network connectivity issue between the client and the server, which may prevent the client from connecting to the server.
- The client may be trying to connect to an invalid or non-existent server address.
In some cases, this error may also occur if the client has exceeded the maximum number of connection attempts to the server.
Solution - Here's How To Resolve It
To resolve the 'memcached unable to locate node' error, you can try the following solutions:
- Check if the Memcached server is running or not. If it has stopped running, restart the server and see if the error persists.
- Make sure that there are no network connectivity issues between the client and the server. You can try pinging the server from the client machine to check if there is any network connectivity issue.
- Verify that the client is connecting to the correct server address. Double-check the IP address or hostname used in the configuration file.
