[postgis-users] Windows Crash

This is in no way a PostGIS problem, certainly nothing we can ever
fix, just something that the particular combination of PgAdmin, the
geometry we are feeding it, and the way the Windows rendering system
are interacting.

My experience has been that these days the thing that causes a modern
operating system (Windows, Linux, whatever) to crash is bad hardware,
usually bad memory, but sometimes other things. Basically, the
operating system itself is usually rock solid until you shake the
foundations it sits on, the hardware.

So basically, all I can offer is the doctor's advice to the patient
who said "doctor, doctor, it hurts when I raise my arm over my
head!"... "don't raise your arm over your head".

In the meantime, if you want to fiddle with things, swapping the order
of your memory in the sockets, changing out the video card, even
changing your screen resolution, might change the interaction such
that you can exercise this particular use case without dropping your
OS to the floor.
