A recent system update to the core glibc package seems to have caused a small number of python apps hosted on our servers to stop working, showing the following in their error logs:

ImportError: /lib64/libresolv.so.2: symbol __h_errno, version
GLIBC_PRIVATE not defined in file libc.so.6 with link time reference

The Apache stack needs to fully stop for this to be fixed. You can do that by starting an ssh session, traversing to the directory hosting your app, and using the `stop` and `start` scripts:

cd ~/webapps/your_app
./apache2/bin/stop
./apache2/bin/start
