I just started a thread on this but for me it has been an ongoing issue for some time, not related to a recent update. I'm currently on 5.8.04 but I've been seeing an intermittent problem for months. See my post about it being potentially storage related.

Hi everyone, this is my first new thread since rejoining following the horrible loss of a year's forum content. For most of the year I've been having an intermittent problem where BI5 (currently 5.8.something) goes loopy, for no obvious reason. I'm in touch with Ken on this but hoping to crowdsource...

Thanks for this thread. I was wondering the same thing, while troubleshooting an issue. Good thoughts here.
