Sounds like you're just tickling the limit. Maybe just increase it with

Use log-queries to see what's happening. You should be looking for

Hi,

First of all a big thank you for dnsmasq.
It's an easy dhcp, dns, read only tftp server to configure.


On a perimeterfirewall the logs gets flutted with the following:
Jan 15 22:32:23 dnsmasq[546]: Maximum number of concurrent DNS queries
reached (max: 150)
Jan 16 00:06:34 dnsmasq[546]: Maximum number of concurrent DNS queries
reached (max: 150)

Note that only one server (gateway) is connected to the
perimeterfirewall.

How can I determine wherein liesĀ  the problem (perimeterfirewall or
gateway)?

In other words: what should I do to understand what's triggering those
messages.

Both the gateway and the perimeterfirewall are on Debian 9 using:
dnsmasq, systemd-resolved and resolvconf(8).

Thanks for your answer.
The issue I'm facing is not occuring all the time and I'm wandering if
'log-queries' could be only passed to dnsmasq when those messages are
logged.

In other words: How can I pass options to an already running instance of
dnsmasq.

I really appriciate any help! :)



Indeed increasing that option does the tric! :)
It's been a fiew days now that I'm not seeing those messages in the log.
I will need to understand why increasing that option works and what are the consequences if any.

Thanks for your time and for your help! :)
