Counts received UDP-Lite datagrams that could not be delivered for reasons other than a missing listener at the destination port. Admins use this as a general receive-error indicator for UDP-Lite, distinct from udpliteNoPorts and udpliteInBadChecksum, when diagnosing why expected UDP-Lite traffic isn't reaching applications. A rising udpliteInErrors count alongside a healthy application listening on the correct port would point an admin toward malformed or truncated datagrams rather than a port-configuration issue.
