Activity streams stalled on www.curriki.org

The streams of activity of groups that one can use for each group are used to display the recent activity on the home page, and on the RSS streams.

Currently, however, several streams are stalled on www.curriki.org.

For example:

• http://www.curriki.org/xwiki/bin/view/Groups/Feed?space=Group_LosAngelesCommunityCollegesDevelopmentalMathExchange&xpage=plain
• http://current.dev.curriki.org/xwiki/bin/view/Groups/Feed?space=Group_CurrikiLeadersGroup&xpage=plain

Although the same software for that part, this does not happen on current.dev. I fear this is something in the back-end!
