I am experinecing a problem with an ML Server runing in a Fusion 5 VM wherby the system hangs completely. A ping from the host will stop indicating any response and the only way out is to shut down the VM through the Fusion 5 menu options. It is not necessary to use force shutdown. The VM does not perfom a logical shutdown it F5 simply goes to the loaded screen where yiu would expect to start a selected VM. The VM will restart if this option is selected.
I believe the problem relates to memory, if I run the VM with a 4G memory allocation I have yet to replicate the problem. At 2G the problem occurs frequently when using applications within the VM.
