I have been seeing this error for the past couple of days. I am not able to make any further deliveries because of this.
This happened when I tried to deliver some dlls and exes(binary files) form my stream to the main stream. The delivery failed because ClearCase cannot merge binary files.
I am not able to "Resume the Delivery" or "Cancel the delivery". The same error crops up all the time.
I tried to look into the Integration view and found the binary files "hijacked". I undid the hijack. But that too did not solve the issue.
Any help would be appreciated.
