Those are not good news. The idea of removing Lucene is to clean up a

XWiki/XWikiPreferences?editor=globaladmin§ion=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)...

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 -

Any idea? Thanks! Hi!

As i said this error has absolutely nothing to do with Lucene plugin
and if you have it you have a serious issue.

I already seen this error but only when running tomcat in Eclipse and
each time it go away when i restart and I have absolutely no idea what
could be the cause. BTW in my case when i get that there is a lot more
that Lucene which does not work.
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!
