Frequent problems with vmware server gui

I get http 1209 and 0 errors frequently and randomly when select different options in the gui.  Sometimes it will behave the entire session, other times it will halt with this error and I have to login  5 times in 3 minutes.  It will also happen randomly when creating a vm and have to start over again.  2.0.2 was just released yesterday but hasn't been posted yet for download; not sure if that will fix the issue.  I'm one step away from wiping it and installing the free ESXi since that has worked out good so far in my test environment.

I'm also seeing messages like this appear in the log (/var/log/vmware/webAccess/proxy.log):

That just happened after getting HTTP 0 error.

I log in again, I click a vm on the left, and now it says ServiceNotAvailableException: Web service not available.

This just appeared in the log:
