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.

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.

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
