So i have read up on similar questions but i haven't found anything that i fully understand yet.

I have a server which is crashing every few days and I am trying to work out where the problem lies. The software is running in an environment supplied by the customer and i need to know if we are the problem or windows/the network.
My question is... RMI registry, Is that something that java creates or is it something that exists in windows anyway? Why would a connection to localhost suddenly become unavailable or refused? Is there anything that i can do to troubleshoot immediately?
The RMI configuration is here:
<RMIService>
<class>com.s.i.system.RMIService</class>
<server name="Server">
<host>localhost</host>
<timeout>0</timeout>
</server>
</RMIService>
Here is the error that is created in the logs.
