Yes.. turning off the stats works.
Otherwise you'll have to wait until the next release. This issue is
fixed in this release.
Much better email Filipe ! It shares info because we learn about what
you do with XWiki !

  Do you need to have the stats service running? if not,
I think turning
 that off will get rid of the error.

  G'Day mates,
 This time I will try to be more complete.
 So, I'm getting a error and decide to investigate.
 I'm using the least Xwiki version, 0.9.840, and this version is
 working fine with 3 user.Leaving another obstacles that I'm getting,
 every thing is running OK. This 3 users are admin users. Until this
 point, xWiki is working OK. But I'm tried to use another user,
 different of admin user.
 My problem starts here. When I navegate with this common user, in
 every page, show the same error. The error:
 com.xpn.xwiki.XWikiException: Error number 3213 in 3: Exception while
 deleting object XWiki.Mega
 Wrapped Exception: possible nonthreadsafe access to session

 I tried to close some classes in Log4J, but I'm don't confortable
 with this masked errors.
 When I put the source in Eclipse to debug, I found where this error
 is "Blowing up". In
 com.xpn.xwiki.stats.impl.XWikiStatsServiceImpl.notify( )say it be
 necessary to delete the oldObject because the ID info have changed.
 Why do I need to delete this old object? This is occurring only in
 simple users. In admin mode this error don't happens.
 I'm looking for this error in xWiki mail list and Ludovic said that
 is a know problem and already fixed, but this answer was in december
 2005 and the 0.9.840's version was build in september 2005. Are there
 anything that I can do to solve this problem in short-term? I'm
 thinking in remove the throw Exception. This short solution will be
 have big impact in xWiki?
 Cheers,
 Filipe Fumaux
