Hello misc@!
I have a router (peaking at 70Mbps of aggregated traffic) that acts as a
recursive internal DNS server too (this configuration will die
soon, as my traffic is growing), but Unbound keep saying, in
/var/log/messages:
Dec 30 09:57:07 myhost unbound: [3873:0] error: can't create socket: Too
many open files
Dec 30 09:57:08 myhost last message repeated 20284 times
Dec 30 10:26:48 myhost unbound: [3873:0] error: can't create socket: Too
many open files
Dec 30 10:26:50 myhost last message repeated 24896 times
Sometimes it says:
Dec 27 21:49:19 myhost unbound: [2565:0] notice: sendto failed: No buffer
space available
I have:
kern.maxfiles=16384
kern.somaxconn=16384
And in login.conf:
daemon:\
:ignorenologin:\
:datasize=infinity:\
:maxproc=infinity:\
:openfiles-cur=4096:\
:openfiles-max=8192:\
:stacksize-cur=8M:\
:localcipher=blowfish,9:\
:tc=default:
unbound:\
:ignorenologin:\
:datasize=infinity:\
:maxproc=infinity:\
:openfiles-cur=8192:\
:openfiles-max=16384:\
:stacksize-cur=32M:\
:localcipher=blowfish,9:\
:tc=default:
With many resources just for Unbound, how can it keep complaining?
Thandk you in advance, and happy new year!
Raimundo Santos
