Solr runs as a webapp (think .war file) inside a servlet container (e.g. Tomcat, Jetty, Resin...). It could be that the servlet contan itself has a bug that prevents it from responding properly after a while. If you have other webapps in the same container, do they still respond? Can you got to *any* of Solr's "pages" (e.g. admin page)? Anything in container or Solr logs?
