VMware shutdown issue

After exiting my VMware program, and then trying to shutdown 9.0, the shutdown process "locks" on a message, something like, "netcenter_vmnet1 waiting to free vmnet1 open=2". I can go back and copy it down if necessary but am leery of it. Message repeats endlessly until I hit reset key. Resetting during shutdown seems like a foul idea, and indeed when re-booting part of the filesystem check ran a series of 903 messages about, I think, some file system repairs. I know this is all pretty vague but if anybody has seen something similar I would appreciate some direction before going thru all this again. Thanks for any suggestions. Richard
