[Dnsmasq-discuss] Max num of concurrent dns reached troubleshootting

[john doe]

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 lies  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).

-John
