Tim, et al: Well, that was it! I have been using the same tomcat config for years, and it appears that it worked OK under older versions of DSpace, but not under 5.1. I merged all of my stuff under the localhost config and now I no longer get the write lock error. My DSpace 5.1 is now up and running.
Thank you all!

You have two <Host> entries defined, which look to me like they are loading the same webapps: 1. <Host name="localhost"> is configured to load *everything* under the "webapps" subdirectory. 2. <Host name="ecommons-test.library.cornell.edu"> is then configured to load "webapps/xmlui" and "webapps/jspui" So, essentially, between these two Host definitions, it looks like you are telling Tomcat to load both the XMLUI and JSPUI *twice*. Could you try commenting out one of your <Host> definitions and rebooting Tomcat? I wonder if that would resolve the Solr lock issues. In general, with the setup you are using, you really only need to either set "appBase='webapps'" OR define individual <Context> tags per webapp. You don't need to do both. As for your other question, I'm not sure why this work work on older versions of DSpace and not in DSpace 5.1. Perhaps it has something to do with the fact that we upgraded Solr to the latest version in DSpace 5.1. Maybe the latest version of Solr is less forgiving about multiple apps writing to it simultaneously. - Tim On 4/9/2015 8:40 AM, George Stanley Kozak wrote: > Tim and Graham: > > Here are excerpts from my tomcat sever.xml file (again, this works OK under > DSpace 4.3 and lower): > > <Engine name="Catalina" defaultHost="localhost"> ... > <Host name="localhost" appBase="webapps" > unpackWARs="true" autoDeploy="true"> ... > <Host name="ecommons-test.library.cornell.edu" debug="0" > unpackWARs="true" autoDeploy="false"> ... > <Context path="" docBase="[tomcat]/webapps/xmlui" /> ... > <Context path="/jspui" docBase="[ tomcat]/webapps/jspui" /> > > Do you think that this kind of configuration could cause the problem I am > observing?
