I had similar problem when I started Tomcat via SSH, and then I improperly closed SSH without "exit" command. In some cases (OutOfMemory) memory is not enough to generate log (or CPU can be overloaded by Garbage Collector to such extent that you will have to wait few days until LOG will be generated) - but process cant' disappear... Process can't simply disappear... if it is JVM crash you should see dump file (you may need to set specific option for JVM to generate dump file in case of crash) > -----Original Message----- > From: athir nuaimi [mailto:at...@nuaim.com] > Sent: November-15-09 1:46 PM > To: solr-user@lucene.apache.org > Subject: solr stops running periodically > > > We have 4 machines running solr.
