Well, the query ofcourse is strange to do. Most likely the repository crashes because of lucene is loading all terms in memory. It thus also depends on the size of your repository. If you take a look at a pid file i suspect you seeing all memory beeing eating up by lucene. What are you trying to achieve anyway?
