[Bug 1675436] Re: After Security Updates PHP 7 Randomly stops resolving DNS

[Chris French]

I just ran apt-get update and apt-get upgrade on the one of the servers,
I will monitor for a little bit to see if it does it again or it that
brings up any other issues.

If there is no issues, but I will update the rest and report back

  After Security Updates PHP 7 Randomly stops resolving DNS

Status in glibc package in Ubuntu:
  New

Bug description:
  I think this is related to this

  https://people.canonical.com/~ubuntu-
  security/cve/2015/CVE-2015-5180.html

  I have 10 servers, randomly  one will start having this issue. it will
  be unable to resolve DNS. Curl will all of the sudden start reporting
  in newrelic about being unable to resolve host names, and it will
  throw SSL invalidation errors.

  restarting will fix the issue and it might be good for several more
  hours.

  I have spoken with rackspace techs and they reported to me that this
  was a bug related to ubuntu and a recent update so I thought I would
  reach out and see if there was any way I could help.
