Subject Re: Solr 1.1 HTTP server stops responding
Date Fri, 27 Jul 2007 14:39:34 GMT
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?

Hi Otis.

I'm filling-in for the guy that installed the software for us
(now he's long gone), so I'm just getting familiar with all of
this.  Can you elaborate on what you mean?
