comment Auto-Sanitizing illegal PostGIS WGS84 (lat, lon) coordinates
You should note that for some values of 4326 your first coordinates are illegal and the second ones are valid. If in doubt don't use 4326

comment Settings for GeoServer: large WMS png request failing
depends on how many features in the layers you are trying to draw and how many featurestyles there are in the slds for each layer. It can be 3 or 4 times the number of features for a road layer (i.e. with casing) then multiply by the number of layers by the pixel size.
