| I'm trying to setup a syslog server to serve a large group of servers.
| For the syslog daemon, I have chosen rsyslogd, and the backend is mysql (on
| a different machine).
| The machine has 2 Intel Xeon 2.80GHz CPUs, and 1GB of RAM, and it is
| running FreeBSD 6 (6.0-STABLE).
| The problem is, that I see a lot of UDP packets being dropped:
without any tweaking :
# netstat -s -p udp
750858021 datagrams received
0 with incomplete header
0 with bad data length field
0 with bad checksum
20003 with no checksum
142075741 dropped due to no socket
1152246 broadcast/multicast datagrams dropped due to no socket
1729027 dropped due to full socket buffers
0 not for hashed pcb
801662 datagrams output
it's been up for a bit, and I don't use syslog but minirsyslogd, which is in
the ports tree I believe.
CPU: Intel(R) Celeron(R) CPU 2.40GHz (2400.09-MHz 686-class CPU)
