OK, this is a strange one. I just completed a pretty difficult upgrade of our DSpace instance from 1.4.2 to 1.5.2 and everything was working pretty well. I guess it still is. You can see the result here:
http://dlynx.rhodes.edu My big outstanding issue came after I rebooted the server to give it one last kick of the tires before calling the whole thing done. After the reboot, everything came back up, but the Java process that is the Handle Server (the thing that knows to serve up http://dlynx.rhodes.edu/jspui/handle/10267/2423 when you hit http://hdl.handle.net/10267/2423 to view an object) has stayed at 100% CPU. Oddly, during the process of getting the 1.5.2 dspace.cfg correct, I was restarting Tomcat and the handle process over and over again, and the handle process never did this 100% CPU usage thing. Only after I shutdown the machine and cold-started it did this 100% CPU issue appear with the handle process. Currently, if I kill the process and then restart it using our standard /archive/dspace/bin/start-handle-server it will race up to 100% and stay there. While the high CPU usage is a concern, it doesn't appear to affect the resolution of handles or DSpace or anything else, other than just the unnecessary CPU cycle. I can find nothing in any of the logs (handle server, tomcat, or DSpace) that would give a clue as to what is going on. Here is what the handle processes look like with the ps command: [...@dam ~]$ ps -ef | grep handle dam 3669 1 0 17:25 ? 00:00:00 /bin/sh /archive/dspace/bin/dsru n -Ddspace.log.init.disable=true -Dlog4j.configuration=log4j-handle-plugin.prope rties net.handle.server.Main /archive/dspace/handle-server dam 3679 3669 99 17:25 ? 00:07:20 java -Xmx512M -Xms64M -Dfile.enc oding=UTF-8 -classpath :/archive/dspace/lib/activation-1.1.jar:/archive/dspace/l ib/bcmail-jdk14-136.jar:/archive/dspace/lib/bcprov-jdk14-136.jar:/archive/dspace /lib/commons-cli-1.0.jar:/archive/dspace/lib/commons-codec-1.3.jar:/archive/dspa ce/lib/commons-collections-3.2.jar:/archive/dspace/lib/commons-dbcp-1.2.2.jar:/a rchive/dspace/lib/commons-fileupload-1.2.1.jar:/archive/dspace/lib/commons-io-1. 4.jar:/archive/dspace/lib/commons-lang-2.2.jar:/archive/dspace/lib/commons-loggi ng-1.0.jar:/archive/dspace/lib/commons-pool-1.4.jar:/archive/dspace/lib/dom4j-1. 6.1.jar:/archive/dspace/lib/dspace-api-1.5.2.jar:/archive/dspace/lib/dspace-api- lang-1.5.2.1.jar:/archive/dspace/lib/fontbox-0.1.0.jar:/archive/dspace/lib/handl e-5.3.4.jar:/archive/dspace/lib/icu4j-3.4.4.jar:/archive/dspace/lib/jargon-1.4.2 5.jar:/archive/dspace/lib/jaxen-1.1.jar:/archive/dspace/lib/jdom-1.0.jar:/archiv e/dspace/lib/jempbox-0.2.0.jar:/archive/dspace/lib/log4j-1.2.14.jar:/archive/dsp ace/lib/lucene-analyzers-2.3.0.jar:/archive/dspace/lib/lucene-core-2.3.0.jar:/ar chive/dspace/lib/mail-1.4.jar:/archive/dspace/lib/mets-1.5.2.jar:/archive/dspace /lib/oro-2.0.8.jar:/archive/dspace/lib/pdfbox-0.7.3.jar:/archive/dspace/lib/poi- 2.5.1-final-20040804.jar:/archive/dspace/lib/postgresql-8.1-408.jdbc3.jar:/archi ve/dspace/lib/rome-0.8.jar:/archive/dspace/lib/tm-extractors-0.4.jar:/archive/ds pace/lib/xalan-2.7.0.jar:/archive/dspace/lib/xercesImpl-2.8.1.jar:/archive/dspac e/lib/xml-apis-1.3.02.jar:/archive/dspace/lib/xmlParserAPIs-2.0.2.jar:/archive/d space/config -Ddspace.log.init.disable=true -Dlog4j.configuration=log4j-handle-p lugin.properties net.handle.server.Main /archive/dspace/handle-server dam 4682 4647 0 17:33 pts/1 00:00:00 grep handle [...@dam ~]$ I think we are running version 6.2.5_02 of the handle server. Has anyone ever seen anything like this? Any clues as for what could be causing it or how to fix it? BTW, are others occasionally getting a "dspace.org This site is down for maintenance. Please check back again soon" message when going to http://www.dspace.org ? The wiki appears to be up and fine, but the main website gives this message quite a bit, at least today and yesterday. -- Stacy Pennington Rhodes College penning...@rhodes.edu (901) 843-3968 ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
