Memory Leak?
------------
Key: GEOS-3219
URL: http://jira.codehaus.org/browse/GEOS-3219
Project: GeoServer
Issue Type: Bug
Components: WCS
Affects Versions: 1.7.5
Environment: 1.7.5 - windows Vista
Reporter: Jonathan
Assignee: Andrea Aime
Priority: Critical
I have a very large GeoTIFF (1.2GB) I have added to GeoServer as a coverage.
This one -
http://ueod-globe.net/globe/TrueMarble_GeoTIFF/TrueMarble.250m.21600x21600.H4.tif.gz
(8MB download, nicely compressed because most of it is ocean).
I tried to download the dataset using WCS (this URL:
<http://<host>:8080/geoserver/wcs?request=GetCoverage&version=1.1.1&identifier=j2:TrueMarble.250m.21600x21600.H4&SERVICE=wcs&FORMAT=image/geotiff&boundingbox=-90,135,-45,180,urn:ogc:def:crs:EPSG::4326>
) - sure enough it returns the image, but I cancel before it starts
downloading. GeoServer then proceeds to fill it's RAM quota (1gig!) and never
frees it, with the console giving the OutofMemoryError and Process Explorer
reporing Geoserver is sitting on 1.1 to 1.2Gig of RAM (but not actually doing
anything - no CPU processing, no disk access, nothing).
I restart GeoServer, and try a smaller dataset (180MB geotif). I use the exact
same URL changing only the identifier. This one /should/ return "no
intersection in BBOX" because there's no data in the given co-ord range, but it
does return data. An 80MB EML file (whatever that is) that contains something
like this:

As well as that, the GeoServer instance suddenly starts using 900MB of RAM
which doesn't get cleared when the image has finished being transferred. It's
now about 5 mins after the image was transferred and I've not made any more
requests to the Geoserver for anything, yet the 900MB is still taken. Almost
certainly a memory leak
Note - these are my Java starting parameters:
%RUN_JAVA% -Xms128M -Xmx1024M -XX:PermSize=64M -XX:MaxPermSize=256M
(the system has 4GB of RAM).
