Zooming very closes makes the server use too much memory

[ksgeograf]

Simple map, using only SDF data sources. Only visible layers is buildings.

Zoom to a very low scale, ea: 1:3.

The memory usage jumps with 1GB+ and my machine starts swapping.

The viewer should prevent such low zooming, but the server should not perform badly.

I can reproduce this defect and am working with Traian on a fix. May be same root cause as ticket 459.

[jbirch]

have this and/or 459 been addressed; can they be closed?

I think this ticket and #459 can now both be closed. See discussion notes in #459.
