SV: [mapguide-users] Grey image after some time in MGOS 2.0

[Kenneth, GEOGRAF A/S]

I have seen this as well.
It happens less frequently with SDF than with OGR layers.
I have not yet had a reproduceable way of making the error appear.

Could you create a trac ticket, and possible enter descriptions for 
setting up your "load test"?
