Hi,
first of all, even a moderate and occasional error ratio is not acceptable from an expensive circuit like E3, and should be reported as faulty until fixed. However, I think you are already aware of that.
This said, as workaround, you can use the embedded event manager to monitor the error count and shutdown the interface on reaching a threshold.
Unfortunately, EEM is not the easiest thing to configure, and the more advanced form (that should not be required in your case) have been introduced only in recent IOS.
You can start with the documentation:

Hope this helps, please rate post if it does!
