So based on your earlier story about scan thread priorities the problem
might also be related to the medium priority callback thread cbMedium,
which is a general facility and could be used for any number of things
inside either the IOC or the application. If you can run spy during
boot-up that might confirm that one way of the other.
Whichever thread it turns out to be, getting a stack trace of the thread
at the time is probably the next most useful thing you could do.
