LEM Reports Run Endlessly

I am running LEM 5.6 and when I launch a report through the Reports Console, it seems to run endlessly.

I should mention that I am new to LEM; the installation has only bee up for about a week or two.

Support is telling me that dev is working on a known iossue with slow reports.  However this is not slow; it just runs endlessly.

I maybe have 30 Windows servers sending data to LEM.

Any thoughts or suggestions?
