Zitat von [email protected]:
I was setting up local_unbound (the built-in instance of unbound in
FreeBSD 10.x). However, I had a conf file that I had a much more
customized from a previous install of the stock unbound I had on
earlier box.
When I tried to transplant the more elaborate conf and have
local_unbound run it, I got the following errors:
[1437336832] unbound[69115:0] warning: too many file descriptors
requested. The builtin mini-event cannot handle more than 1024.
Config for less fds or compile with libevent
[1437336832] unbound[69115:0] warning: continuing with less udp ports: 211
[1437336832] unbound[69115:0] debug: switching log to syslog
I bit-by-bit added on section at a time to unbound.conf until I
found the offender was this entry:
# number of threads to create. 1 disables threading. This should
equal the number
# of CPU cores in the machine. Our example machine has 4 CPU cores.
num-threads: 4
Why would threading cause these errors? What is the default setting
when the entry is commented out?
To my knowledge the number of threads is 1 by default. For the
relation of file descriptors with threads and other settings have a
look here: http://www.unbound.net/documentation/howto_optimise.html
