   Hi Gregor,
   Yes, it is the same issue.
   I'm currently uploading the latest test tempates to:
   http://packages.shapeblue.com/systemvmtemplate/public-testing/41121rc0/
   
   Latest have the date of the 10th Dec on them.
   
   They include
   - adding cache back pressure 
   - setting a target minimum amount of free memory (reduces caching)
   - reducing the number of startup Apache HTTPD threads/processes
   - tighter control over the starting of guest daemons for hypervisors
   - fix for misconfigured vmware tools conf file
   - explicit ordering of cloudstack start processes
   - and proper termination of startup services
   
   The memory usage is much less..
   
   I don't think that hammering with ssh connections is a useful test. instead i create a network with a couple of VMs and then constantly add and remove firewall rules and port-forwarding rules to them. one every couple of seconds to ensure that they are separate connections.
   
   I have left this running for 3 days with no swapping on a 256MB VR.
