Hello,
I have a DNS server with a lot of traffic. After just a couple of
minutes of resetting the netstat -s counters, I get the following output:
130670 datagrams received
0 with incomplete header
0 with bad data length field
1 with bad checksum
30 with no checksum
0 dropped due to no socket
12 broadcast/multicast datagrams dropped due to no socket
4226 dropped due to full socket buffers
0 not for hashed pcb
126431 delivered
136753 datagrams output
As time goes by, the "dropped due to full socket buffers" number goes up.
I have increased the sysctl variable net.inet.udp.recvspace to 100000,
up from about 40000. This did not make any difference, the number goes
up with time.
The server is running FreeBSD 4.6 RELEASE with Bind 9.2.2.
I went through the newsgroups and did not find any solutions to this
problem.
Any help will be greatly appreciated.
