Hi all,
I'm increasingly experimenting with serving rasters through geoserver,
and getting some severe memory problems recently. Part of an example
stack trace follows below.
Problem is that after some time of serving, geoserver gets out of heap
space, and just serves error in the tomcat log instead of images.
Tomcat is started with -Xmx2000m, so I'd say heap space should be
enough. JAI and JAI-imageio are installed, cvs versions of not so long
ago. Jdk is sun-jdk-1.5.0_09. Geoserver is 1.5.x of yesterday, geotools
is 2.3.x of yesterday.
CoverageStores usually are tiled geotiffs (rgba) with internal
overviews.
wms usually requests png rgba images.
I'd like to know if there are ways to (memory) optimize this setup, and
besides that if there is some way to monitor and/or debug memory usage
by geoserver.
Things I thought I could try (please comment):
- update jdk to 1.5.0_10
- maybe update jdk to 1.6? Any issues to be expected?
- use geotools' mosaic and pyramid builders instead of geotiffs?
- ???
Below is some example stack trace part, though I doubt it is of much
use...
Cheers,
Vincent.
