Severity: 2-Critical


When an interface has a very long name, it is possible for various functions to overrun the memory allocated and cause other problems. The other problems will vary, depending on what is running at the time of the memory overrun.


Possible loss of client connectivity or random errors possibly resulting in cores. Traffic disrupted while tmm restarts.


This can occur if the interface is associated with a non-default route domain.



Fix Information

Long interface names no longer cause issues.
