Warning: increased limit(open files)

Unbound
1

Hi,

On starting unbound I get:

[1354535821] unbound[13607:0] warning: increased limit(open files) from 16384 to 33142

Shouldn't this be sent tot syslog or logfile?

Hi Leo,

Ah, that explains.

Still, it is unexpected to have something thrown out when it is 'only'
a warning.

What do you expect us to do with this warning?

It increases ulimit while it holds root privileges. It then
chroots and drops user privileges. It does not have the syslog
or logfile open to log to at the time when this call happens.

Unbound is using root privileges to gain extra OS resources, resources
that are limited for normal processes. This messages is to tell you
that it did so, and how many resources it took. What you do is up to
you: simply ignore it, calculate the number of buffers on the system,
configure unbound to use less resources, ... (or set ulimit higher
beforehand, and you get no warning).

Best regards,

Check. ulimit -H -n $number

Thanks.

So far Unbound has been a pleasure to compile and configure, thanks for
a great product and your outstanding support.
