I have experienced same issue, i resolved the problem. Howerver we use Plesk Panel. Via Plesk I changed PHP version and then changed it back to same version. Problem fixed, probably some PHP config got rebuiled by that.

what is a "ubuntu server"? :-)

joke aside - and hence when everything but not PHP is update dand PHP has a problem than it#s not the responsibility of PHP and when you get your PHP from your distribution it is NEVER a php upstream bug wehan some random package is updated and php breaks

Hello,
I saw this same behavior in 8 Ubuntu servers, with automated security updates.

Thanks to all for the helpful resources - 

libc version 2.19-0ubuntu6.11 resolves the issue introduced in 2.19-0ubuntu6.10.

According to https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/1674776

The cause might be the fix of CVE-2016-3706: getaddrinfo: stack overflow in hostent conversion.

Bug 1674532:
After installing the libc6_2.19-0ubuntu6.10_amd64_udeb package during the automated install of ubuntu 14.04.5, the system was suddenly unable to resolve hostnames via dns. Installing -0ubuntu6.9 resolved the issue. Reinstalling -ubuntu6.10 broke the system again.

I note that -ubuntu6.10 was recently added to the archive.

I am currently unable to install Ubuntu 14.04.5.
