Enabling 'Register DHCP leases in the DNS Resolver' causes crash



  • I had disabled 'Register DHCP leases in the DNS Resolver' recently due to DHCP/DNS taking way too long to restart when a host joins the network. For whatever reason, I wanted to re-enable this feature so I can do host lookup. But when I enable this, pfSense crashes. The logs I get after I enable it are;

    Dec 2 10:33:13 	kernel 		swap_pager_getswapspace(1): failed
    Dec 2 10:33:13 	kernel 		swap_pager: out of swap space
    Dec 2 10:32:48 	kernel 		swap_pager_getswapspace(1): failed
    

    I have to then force reboot the device. Can someone help me figure out why this is happening?

    Running XG-7100 running 2.4.4



  • Good !!
    You managed to make live easy for the one who replies to your question.

    You had to :

    which means this isn't 'unbound' only that restart, but probably some packages with a big payload.

    Now, it's no more 'big wait', but clearly :

    @bhjitsense said in Enabling 'Register DHCP leases in the DNS Resolver' causes crash:

    swap_pager: out of swap space

    You ran out of memory AND swap memory.
    That's the moment any system would just die ...

    Solution : more (far more) memory. Bigger processor.
    Or remove the load (packages).
