When you upgraded, what did you change in the config? One thing I am looking for specifically in this situation is the updateLog config. It is a good idea to turn this on in the new version, but depending on how you do your commits, this may make restarts take a very long time. Here's a wiki page that discusses the possible problem in some detail: http://wiki.apache.org/solr/SolrPerformanceProblems#Slow_startup Thanks, Shawn
