Yes, but as said, you can tune different parameters to make it harder to happen, like rising qthreshold, reducing cprange, setting a lower nice value for ulogd. > 2. What ENOBUFS does depend on?

Rising the value to the infinite is not either a solution, you'll hit ENOBUFS sooner or later. -- "Los honestos son inadaptados sociales" -- Les Luthiers -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
