Jul 9 01:56:43 kernel: 603.390440 [3911] netmap_transmit em1 full hwcur 221 hwtail 95 qlen 125
-
I got these randomly but very often seconds apart.
I scratched my head with this because I only got it on em1 and not em0 as well.
I have Suricata running inline on both.
This is my loader.conf
kern.cam.boot_delay="10000"
kern.ipc.nmbclusters="2000000"
kern.ipc.nmbjumbop="524288"
kern.ipc.nmbjumbo9="524288"
dev.em.0.fc="0"
dev.em.1.fc="0"
dev.netmap.buf_size="16384"
autoboot_delay="3"
hw.usb.no_pf="1"
net.pf.request_maxcount="2000000"After I changed this; dev.netmap.buf_size="16384" from "2048" to first "4096" to no avail, I upped it to "8192".
That made the netmap become less frequent. I upped it once again to "16384" and so far so good.
No errors in the logs and on the console so far.
-
I was a little to hasty.
Errors coming again...
Despite changing the dev.netmap.buf_size="16384"
Output of sysctl -a | grep netmap still looks the same and no change to any values.
Its like its hardcoded and cant be changed??
