In Intel® Stratix® 10 devices and Intel® Agilex™ devices, when injecting more than 8 errors continuously without the Read EMR using the Fault Injection Debugger, this warning message is displayed.
This is because the Error Message Register (EMR) can only store up to 8 messages.
To work around this, click Read EMR to read out error messages and clear the Error Message Register (EMR). Then the warning will not be issued unless more than 8 errors are injected again without the Read EMR.
