Hi, on a jail with quite a lot of somewhat bursty network traffic I get warnings from netdata recently about packets being dropped because of net.route.netisr_maxqlen being to small. Before I start setting this value to some random value I'ld like to find out what it actually means. A search for documentation turned up nothing; a look at the sources found that it is used for the size of a "software interrupt queue" in epair(4). But what does it mean? And does this give me enough information to find a good value to set for this sysctl? Wolfgang
