Hi,
I've got a machine running syslogd, DNS, DHCP, flow-capture, and other
assorted UDP-loving programs. Occasionally, they all stop working.
The machine has been up for a couple of hours now, and I see:
ns1/etc;netstat -s | grep full
Warning: sysctl(net.inet6.ip6.rip6stats): No such file or directory
122066 dropped due to full socket buffers
ns1/etc;
I've doubled kern.ipc.maxsockbuf a couple of times now, and yet it
still happens.
After some help from questions@, I'm pretty sure that the culprit is
syslogd.
udp4 0 0 *.67 *.*
udp4 43414 0 *.514 *.*
udp4 0 0 *.49661 *.*
Things run perfectly for a while, and then we suddenly stop answering
UDP requests. We continue not answering UDP requests until I restart
syslogd.
syslogd -d didn't give anything interesting.
I'm now running syslogd -n, to see if that helps. I'm also restarting
syslogd every fifteen minutes, to ensure that the problem can last no
longer than 14 minutes. :-)
Anyone interested in why syslogd is not draining the queue?
Thanks,
==ml
