[ms4w-users] new server crashes generating tiles

[Nick Ullman]

Hello again!

I can confirm that it is not MS4W.  While the IT guy was standing here
saying again and again that it must be 'that software' I did a
right-click-properties on the ka-map cache folder to show him how many
files were successfully created and the machine crashed.  'that
software' wasn't running at the time.

So, something is wrong with the raid controller and/or the drivers for
it.  Just decompressing the ms4w.zip on that drive takes over two and a
half minutes (compared to 15-20 seconds on my laptop) and that activity
can crash the system too.  Again, in front of the IT guy, the Microsoft
.zip extractor crashed the system.  I believe I have his attention now!
:-)

Once again, thanks for your suggestions!  This is now officially a
Windows driver and/or hardware issue.

Regards,
Nick

It's strange. HP hardware usually has excellent support.
Here are a couple of links to help you diagnose the BSOD:

I am quite sure mapserver isn't the cause and if I were in you I'd
look for defective RAM or even overheating (which can be quite common
if the server is housed in a badly air conditioned rack).
