  This problem seems to strike back on me.
 Whenever I open the users page .../XWiki/aha
 it sends the garbage collector to infinity - restarting Tomcat is the only
 help.
 However its an older wiki: XWiki Enterprise 2.3-milestone-1.27899
 This is the .xar:

 Thanks for your support 
I don't know what the problem is but do you have the same issue with XE 2.7.1 or XE
3.0M3? (would be good to know if there's something to fix)
Thanks

PS: Note that the strategy for xwiki developers is to support only the last 2 versions (ie
2.7.x and 3.0 as of now).
See 
http://www.xwiki.org/xwiki/bin/view/Main/Support (I've just added the info box)
That said, you may be lucky and find someone to help you with your specific problem on a
2.3M1 release.
