Hi, I am currently testing wrapper 3.4.0 on solaris 64 bit machine. Under regular "physical" machine its already working for days and is fine (tried that on a couple of machines). However if i run the wrapper under vm instances (of vmware) i get abnormal shutdowns always both to my server and to the wrapper (after about 2 hours both process are down). I'm attaching relevant logs: Note that I tested a configured vmware for reservation of cpu to one of the vm instances then on that vm instance it seems that I don't have this shutdown, i have multiple vm virtual machines on the same physical machine and the shutdown happens on all of them (except for that instance with that cpu reservation). I would like vm configuration to be working as well because I'm thinking of having such a configuration possibly in future in production. I also saw this over the web: http://old.nabble.com/JVM-appears-hung:-VMware,-verbose-garbage-collection-td13470076.html Here are relevant logs if you could provide me with information of why these abnormal shutdowns are happening: INFO | jvm 1 | 2010/04/20 19:43:30 | WrapperManager Debug: Java VM Vendor : Sun Microsystems Inc.
