Re: misc/53421: 8.0_RC2 named has resource issue

Hello,

I don't know if this has been fixed in netbsd-8, but I found a 
"solution". By compiling the standard bind software with the following 
options, I have kept my name server up since Dec. 4th. Here's the info 
from named -V:

GameofThrones:/var/named# /usr/local/sbin/named -V
BIND 9.12.3 <id:6c8e92c>
running on NetBSD i386 8.0 NetBSD 8.0 (GENERIC) #0: Tue Jul 17 14:59:51

UTC 2018  
mkrepro%mkrepro.NetBSD.org@localhost:/usr/src/sys/arch/i386/compile/GENERIC i386

And, just in case someone wanted proof that my name server has been up 
this long:

GameofThrones:/var/named# ps awux | grep named
root     15764  0.0  4.3 62108 44208 ?     Ssl   4Dec18  92:48.36 
/usr/local/sbin/named

Now I should note that I'm using forwarders in my named.conf file, but I 
was experiencing the same problem as reported in this bug. Namely named 
would print the following error to the log file and then no longer 
answer UDP requests:

dnslog.txt.72:23-Nov-2018 06:09:23.130 UDP client handler shutting down 
due to fatal receive error: not enough free resources

I hope this helps in some small way.

Thanks,

Jason M.
