Error message in collaboration IP list on Query IP: Index out of bounds... parameterName: chunkLength; IP status Failed

Sometimes an IP seems to lock up after it has been working fine for a while. Then once it fails with this error message, the IP is unable to resume, even though the source query works fine and the job can run through the Workbench. No errors are logged in a trace of EventManger. A restart of the EventManager clears these errors.


Some googling suggests that a non-thread-safe StringBuilder might be to blame. We are on v7.9.3. Anyone else experiencing the issue?
