DNS Forwarder - override an entire domain - high CPU usage ~80%



  • Hi,

    I have got a problem with high CPU uasage of the dnsmasq process.

    WAN –- pfsense1.localdomain1 --- 172.16.0.0/16 --- pfsense2.localdomain2 --- 172.17.0.0/16

    pfsense1 and pfsense2:
    DNS forwarder: enabled
    Register DHCP leases in DNS forwarder: enabled
    Register DHCP static mappings in DNS forwarder: enabled

    pfsense1:
    Domain         IP                 Description
    localdomain2  172.17.0.1  pfsense2 DNS Server

    pfsense2:
    Domain         IP                 Description
    localdomain1  172.16.0.1  pfsense1 DNS

    If I remove this overrides, the CPU usage goes down to normal.
    I had this problems with this two snapshots:

  • Not seeing that and I have domain overrides on several systems. You sure it's the dnsmasq process?



  • Hi,

    I did two screenshots. I entered this overrides and there was no CPU increase for some minutes. Then I did a reboot of both boxes and then there was the CPU increasement.

    The pictures are just from one pfsense, but the other is the same CPU increasement but like i said in my first post with an other IP adresse and domain

    –-edit----
    if I delete the override on ONE box, both boxes got down with CPU usage. If i reenter this override, it takes 2-3min and the the dnsmasq process goes up again.
    I attached the DNS forwarder picture of the other pfsense, too.










  • do they keep querying each other or something? because when you edit one out, both boxes drop in CPU usage…

    Maybe make a pass rule for udp53 with logging and see?



  • Looks like this on both machines:

  • but is it all happening in the same second? (i.e. do you get a boatload of queries when you do one lookup?)



  • Hi,

    I do not need to make one lookup. After the CPU usage of dnsmasq is so high, there are 10 or more dns queries per second. I will try this again without any internet connection, just the two pfsense boxes and one client to view the webGUI.

    –--edit----
    same problem after unplugging WANs and rebooting both pfsense

  • I have to correct something:

    If I delet domain override on pfsense1, then CPU usage goes down. If I delete it on pfsense2, the problem is still there.

    Don't know, perhaps I am too stupid and did a misconfiguration.  ???



  • Yeah you created a lookup loop, host A is using host B to resolve that domain, and host B is using host A, so it infinitely loops, hammering each other to death with lookups.



  • Aaahh, okay…..OSI Layer 8 problem  ::)

    ??? Layer 8?? I didn't know they added a new Layer! When did this happen?
