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

[bhjitsense]

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 :

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).
