Subject: Ring buffer overflow

Hi

 

In an asyn port driver, I get the following message on the IOC shell

 

scanOnce: Ring buffer overflow

 

For now I rarely get this message and the IOC is working fine, but what is the reason behind it? Could the record’s IO is taking more time than the scan time?

 

Best Regards,

Abdalla.
