[Dnsmasq-discuss] Dnsmasq on high load

[Анатолий Мулярский]

Hi list,

I'm using dnsmasq as a caching DNS-server for 2000+ users.
Here is my configuration file:

#bogus-priv
#domain-needed
except-interface = lo
#filterwin2k
leasefile-ro
no-ping
no-poll
user = nobody
#pid-file.
cache-size=9500
dns-forward-max=4000

Periodically I got the message:
dnsmasq[2272]: failed to send packet: Resource temporarily unavailable

Used version of Dnsmasq is 2.72
Compile time options: no-IPv6 GNU-getopt no-DBus no-i18n no-IDN DHCP
no-DHCPv6 no-scripts no-TFTP no-conntrack no-ipset no-auth no-DNSSEC
no-loop-detect

Can someone suggest me how to optimize my configuration for high load
and get rid of the above message?
