Its really simple to reproduce.
Setup an input adapter that gets events from an empty PI point, and is setup to send a CTI every 3 events. Run it with tracing enabled.
Now add a new value at 1am, and a second value at 2pm. The Adapter will automatically send in a CTI (it accounts for the first value as one event). Now add a value at 1:30am (which is before the CTI time). You will get an exception thrown (as it should), but it will keep on doing that forever.
If you want, I can send you the code.
Were you able to reproduce this? Do you need me to send you a sample? When will this be fixed?
This has been fixed in the PI for StreamInsight May CTP
