We use the output from the '/server-status?auto' URL in a few scripts. However at some point the 'Total Accesses' (or 'Requests' in the non-auto report) will overflow and be stuck at -0 instead of wrapping to 0. This breaks some applications (in particular rrdtool) as -0 is not a valid number.
I have reported something similar before (in 2004), but the bug seem to have returned in a different place. See below for my previous bugreport.

The counters itself of doubles, the display is limited to 2Tb currently.
I'll add a better scaling in 1.3.7.
... mod_status is fixed now, ... mod_rrdtool is next
