Thanks to those who offered up suggestions for stopping these messages. I guess I wasn't terribly clear on things. I actually have already rooted this phone, so I am able to disable the process.
What I was asking originally was whether or not the process I suspected, com.htc.vmm, was the culprit, and whether or not there were any known issues I'd run into should I disable it.
No one commented directly on either of those questions, and those darn messages were bugging me, so I went ahead and disabled it using adb and the shell command pm. The messages are no longer coming, and so far there've been no problems with having disabled it.
thanks again,
john
