OutOfMemoryError running in Tomcat

Rate this Message:
Hello, I'm running Geoserver in a Tomcat 5.5.27 instance deployed in a Red Hat Server with 2Gb of memory and JDK 1.5.
Surprisingly, geoserver crashes after a few request, specially when the requested envelope is small (near 100m X 100m). The exception is: Exception in thread "http-8080-Processor25" java.lang.OutOfMemoryError: requested 16 bytes for CHeapObj-new. Out of swap space? and the catalina.sh script for run tomcat has the next options (as I read on: http://geoserver.org/display/GEOSDOC/2.6+GeoServer+in+Production+Environment) JAVA_OPTS="-Djava.awt.headless=true -server -Xms1000M -Xmx1000M -XX:SoftRefLRUPolicyMSPerMB=36000 -XX:PermSize=500M -XX:MaxPermSize=500M -XX:+UseParallelGC" Any advice please? Thank you very much. ------------------------------------------------------------------------------ _______________________________________________ Geoserver-users mailing list Geoserver-users@... https://lists.sourceforge.net/lists/listinfo/geoserver-users |

Thank you very much. There has been a similar thread some time ago: http://www.nabble.com/Apache-Tomcat-crashing...-td18988481.html but in the end I don't think it provided much of a solution, it seems to be related to system level issues. What you can try is to: - upgrade the java virtual machine to 1.6.0_14 - reduce the -Xmx and -Xmx to lower values (512M) and definitely reduce the perm size, seems quite a bit too wide Cheers Andrea -- Andrea Aime OpenGeo - http://opengeo.org Expert service straight from the developers. ------------------------------------------------------------------------------ _______________________________________________ Geoserver-users mailing list Geoserver-users@... https://lists.sourceforge.net/lists/listinfo/geoserver-users |

Hello, I've tried changing this paramters but it goes on crashing :(
One more question. JAI libs could be realated to the problem? I've been thinking that JAI only are used to render coverages but I'm not sure now. Thanks.

Hi,
I've the same problems running in a similar environment in Windows. I tested with other layers (example layers, shapefiles, oracle, .....), always with the same results: Geoserver crashes beacause OutOfMemory problems. I wonder if anybody works with so reduced envelopes (near 100 x 100 m). Must I restrict them? Are they support by Geoserver?

I'm wondering if you're being hit by http://jira.codehaus.org/browse/GEOT-2538 If so, try downloading http://sigma.openplans.org/~aaime/gt-api-2.5.6.jar and replacing the same file you find in the GeoServer install (this patch works if you're using GeoServer 1.7.5, not sure what your version is). As for being able to set limits on the size of the WMS requests, 1.7.5 has some parameters you can set documented here: http://gridlock.openplans.org/geoserver/1.7.x/doc/user/services/wms/configuration.html#request-limits Cheers Andrea -- Andrea Aime OpenGeo - http://opengeo.org Expert service straight from the developers. ------------------------------------------------------------------------------ Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!

Hi, it works much better and there are no requests for exceptions to 25m (width) but I have to pass more tests. Thank you very much
