AG,
I was browsing through the logs on the host that was experiencing the disconnects and noticed something that correlates to the events.
When looking at the /var/log/hostd.log check your logs and see if you can see any message simillar to those;

I may be off here but doing anything i can before VMware gets back to me. Those logs dont really make much sense to me but they seem to follow all the disconnect events that i see.
thanks.
