Memory leak on admin web console

Hi everyone,

I found a memory leak on the admin web console when clicking over User/Groups tab. I think that the page tries to load all the users and this brings to  fill all the memory (8Gb). My environment has about 3M of registered user.

I develop a lot of new feature in order to meet our requirements, but my JSP's knoledge is really basilar so i'm not able to find and fix the issue.

I don't know if this is a known issue. do you know some bugfik about???

Thanks for your help.
