[xwiki-users] Lucene search stopped working

Hi all, The search service in my XWiki Enterprise 1.5M1 installation has stopped working - when you use the search box, the following error is given: A problem occured while trying to service your request. Please contact the support if this happens again. My Xwiki is installed in Tomcat 5.5 on CentOS 5. I just restarted Tomcat, and the following errors have appeared in the catalina.out: INFO: Stopping Coyote HTTP/1.1 on http-8080 Jul 9, 2008 3:30:38 PM org.apache.catalina.core.AprLifecycleListener
