$ mogrify -limit "disk" "20gb" -limit "map" "512mb" -limit "memory" "512mb" -limit "thread" "2" -limit "time" "120" -format jpg -auto-orient -thumbnail "1200x1200>" -strip -quality "60" -colorspace "rgb" -border "0" -bordercolor "white" 0000000079
mogrify: unable to acquire cache view `No such file or directory' @ fatal/cache-view.c/AcquireAuthenticCacheView/121.

If I simply remove "-limit disk 20gb" it converts the image in about a second.

You want 20GB not 20gb and 512MB not 512mb. See http://en.wikipedia.org/wiki/Metric_prefix and http://en.wikipedia.org/wiki/Binary_prefix.

Should we make it case insensitive.

Though I think Mega and milli make have a problem, it is not really a problem in this context.

Or at least give a warning about an unknown suffix.

I have been adding such warnings in IMv7 escape handling, or attempts to set one of the read only escapes.
