My application is displaying a DNC using VPFLayer. From time to time, the
processor goes out to lunch. The java and X (RedHat 8.0) processes are both
contributing to the high CPU loading.
The VPF Properties has been reduced to:
prettyName=VPF Layer
vpfPath=/main/vpf/dnc17
coverageType=hyd
featureTypes=area
area=hydarea
lineWidth=1
lineColor=FFFF0000
fillColor=FF0000FF
searchByFeature=true
I have noticed a couple of things:
1> I have only observed this when zoomed in (1:37500 right now).
2> Not all of the polygons are stable -- like they are constantly being
redrawn at two *slightly* different coordinates. This stops after several
minutes -- and the CPU load drops, too.
3> If I recenter the map (even nearby), this may start up again.
The rendering anomaly does not seem to occur in Windows. I did notice
memory getting chewed up pretty fast, but that is probably one of my bugs.
And ideas?
