 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

 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.
