Would you be able to share packet capture (tcpdump -s 0 -w CAPTURE-FILE, and then the output of CAPTURE-FILE)? Thanks.
As far as I can tell, “getent ahosts large-a.t.enyo.de” results in DNS activity that matches the preconditions in your description, but I don't observe a crash (even with Ubuntu 18.04 LTS and its 2.27-based glibc).
