Joined a new node to my cluster and started node up.  
In the logs I have a warning.

```auto
 The SSL library function CRYPTO_set_mem_functions failed. This is typically caused by the SSL library already being used. As a result the SSL memory allocation will not be instrumented.

```

How do I fix the warning?
