As a tangent, You can run the webapps like solr on separate tomcat instances if this becomes a concern. They seldom need to be restarted as often as DSpace does. In fact, there are very good scalability strategies that are oriented around replicating solr instances across a cluster of tomcat nodes and "sharding" the indexes to improve the performance and scalability of the application.
