What is logged when it cannot find JNA ? 

What is passed to the java service ? Check with ps aux | grep cassandra

It is, but it doesn't load it.
I tried the default package manager version (3.2), the 3.3 and the 3.4 version and this node always say that was unable to load the JNA. I put the jna.jar inside /.../cassandra/lib/ where the other .jar files are.

I have other nodes with the same config (without JNA) and they don't trigger this error.

Is JNA.jar in the path ?

I've been using cassandra for a while, but after a upgrade to 1.0.7, every machine kept running perfectly. Well, except one that constantly throws this error:

The machine does run, but nodetool doesn't connect to the machine for example.

Any ideia from what could be trigerring this?
