In some cases, this error can also be caused by a hardware issue, such as a failing hard drive or corrupted RAM.

Other factors that may contribute to the "Memcached error 47" include issues with network connectivity, an overloaded server, or a bug within the application code. It is essential to identify the root cause of the error to resolve it effectively.

Solution - Here's How To Resolve It

If you encounter a Memcached error 47, one solution is to check the amount of free memory available on the server and increase it if necessary. You can use monitoring tools to analyze the memory usage of the Memcached daemon and find out if it's exceeding its allocated limits.
