We have a box terminating a lot of MPD tunnels from dialup connections. When the modems at remote sites renegotiate due to poor line quality, there will be a pause in the flow of data. Occasionally, the interface on the terminating side will get a "no buffer space" as data is accumulating to be sent out. Is there a way for me to increase those queue sizes so that the server's queue has more room to hold the data until the other end is ready to receive again ? The only sysctl var I could see % sysctl -a | grep -i queue net.inet.ip.intr_queue_maxlen: 50 net.inet.ip.intr_queue_drops: 0 p1003_1b.sigqueue_max: 0 I dont think is related to this issue. These are all netgraph interfaces BTW.
