Hi,
i`m installing geoserver in tomcat7 on an Ubuntu 12.04 Server with only 512mb RAM
This all went fine, but now tomcat7 crashes even before geoserver can be started. Simply a matter of memory.
I have set the max/min PermGen to 512 and Xms /Xmx also to 512.
Is there any possible way to run geoserver on so little memory?
thanks for any tips or tricks

Thanks for the link.
I am aware of the production environment settings. I also know that it is recommended to use 1gb upwards of RAM.
I was looking for a few tips or tricks regarding running in a sub-optimal environment. I have set tomcat7 JAVA_OPTS as written in the production documentation but geoserver still crashes after a few seconds.

This the end of catalina.out
maybe there is another issue here.

Robert,
first remove every service you do not need, no WPS, no format that you do not access, only datbases you need try to make the installation as lean as possible.
Next starting with 128 MB PermGen/MaxPermGen, (may be even 96 MB) and go up in 32MB steps, if 128 does not suffice. Try to minimise the PermGen. Give as much as you can to the heap.
There was a link on this list from somebody pointing to:
http://opengeo.org/publications/geoserver-production/which is a nice summary of geoserver configuration for production.
Then monitor the memory use of the VM :
-Xloggc:somewhere\gc.log
-XX:+PrintGCDetails
I do appreciate the sportsmanship of this attempt to get away with 512 MB RAM, however, compared to the work involved isn't it cheaper to go to to the next shop get some RAM and stuff it in the box?
Cheers
Christian

You probably don't need 512MB for PermGen. If I needed to run GeoServer in 512MB of RAM, I would start by setting JAVA_OPTS like: "-Xmx128M -XX:MaxPermSize=192M" and reducing the size of the Tomcat thread pool (to limit the number of concurrent requests GeoServer will try to serve. You can also do this in a more fine-grained way with the control-flow module:
http://docs.geoserver.org/stable/en/user/extensions/controlflow/index.html, but that would be adding more code and contributing to the pressure on PermGen.)
You can also use JConsole or JVisualVM to keep an eye on memory usage. This is probably most effective if you are also controlling a client, so you can correlate increases in memory consumption with operations (and then configure GeoServer not to offer those operations if you don't need them.)
http://docs.oracle.com/javase/6/docs/technotes/guides/management/jconsole.htmlhttp://docs.oracle.com/javase/6/docs/technotes/tools/share/jvisualvm.html
Note that both JConsole and JVisualVM can operate through an SSH tunnel, so you don't need to expend much of the server's RAM on running them. -- David Winslow OpenGeo - http://opengeo.org/
