D4Science Infrastructure

• It would be better adding 1 GB of RAM each, I've always seen heap memory problems with smartgears nodes with less than 2GB of RAM.
• I also always saw problems when the min and max heap sizes differ. I don't see a reason to use different values, the services live on dedicated VMs and the applications always try to use all the available memory anyway.
• There's also accounting-service3.d4science.org. It's registered on the load balancer, but it's down. If it's not used we should destroy and remove it from the configurations.

sdi.d4science.org tomcat was restarted this morning, before the restart there was a memory warning on nagios.

accounting-service3.d4science.org only had a non working tomcat, now it's on line.
@luca.frosini@isti.cnr.it we add 1 GB of RAM on each node, OK?

yes, please
