Hi! Thomas Mortagne wrote: I'm afraid the we are in trouble here... :-( So, as several issues seems to be related here, I think we have to establish some kind of "strategy" to identify the problems. I'm not a maven, so what I can do are only simple things. So, as it seems Lucene is, for one or other reason crowding catalina.out, I'll remove Lucene Plugin from xwiki.cfg, start a new catalina.out, restart the servlet container and see what messages we do obtain. Please, any other idea? Thanks! Cheers, Ricardo -- Ricardo Rodríguez CTO eBioTIC. Life Sciences, Data Modeling and Information Management Systems

Hi! Thomas Mortagne wrote: Those are not good news. The idea of removing Lucene is to clean up a bit catalina.out. Now, without Lucene plugin, Java is back to normal, XWiki/XWikiPreferences?editor=globaladmin&section=Search is accessible again (even almost useless :-), and we have only a bunch of errors. Here the whole catalina.out some 20 minutes after the start-up and with "normal" use (three, four users browsing some wikis)... http://ftp.ebiotic.net/fromPeat/catalina.out.201010212026.txt Well, now, I have no idea about what to do next. Here the situation: 1. We have a recently migrated farms that is working quite nicely without Lucene. 2. We have the record of an error on Tomcat start-up process that points to a serious issue. I have no idea about what does this mean at this moment. 3. We have some more errors, most of them saying 'com.xpn.xwiki.XWikiException: Error number 11015 in 11: Exception while exporting'. I guess those errors are related with some robot wanting to export pages available for guest in PDF format. I don't know if this error is important or no. I'll report it on Jira. I think that before going back to Lucene, we must to work-out these other exceptions. And perhaps wait until 2.5 is released and try with it. What I don't know is what else could I do to find the root of the "big" error: 2010-10-21 19:57:56,199 [main] ERROR session.ManagerBase - IOException while loading persisted sessions: java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: com.xpn.xwiki.internal.model.reference.CompactWikiStringEntityReferenceSerializer java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: com.xpn.xwiki.internal.model.reference.CompactWikiStringEntityReferenceSerializer ... Caused by: java.io.NotSerializableException: com.xpn.xwiki.internal.model.reference.CompactWikiStringEntityReferenceSerializer ... Any idea? Thanks! Ricardo -- Ricardo Rodríguez CTO eBioTIC.
