A small Ubuntu 13.04 virtual machine instance I run in a cloud environment regularly becomes slow/unresponsive because of a proces called check-new-release. Is there any way to disable this process and maybe run it manually instead?

Try doing

apt-get remove ubuntu-release-upgrader-core

The script that you're seeing running is /usr/lib/ubuntu-release-upgrader/check-new-release, and removing the above package will remove that script completely.

A description of this package is:

ubuntu-release-upgrader-core - manage release upgrades

In the file /etc/update-manager/release-upgrades change Prompt=normal to Prompt=never.

You can also do this through the GUI, but that may not be appropriate for a virtual server.

You can do a manual check for a new release with do-release-upgrade

It is a pain on low RAM servers and 'Prompt=never' did not work for me on Ubuntu 18.04 so what I did (exit code 1 means NO_RELEASE_AVAILABLE):

mv /usr/bin/do-release-upgrade /usr/bin/do-release-upgrade.bak;
echo -n 'import sys; sys.exit(1);' > /usr/bin/do-release-upgrade
chmod 755 /usr/bin/do-release-upgrade
# chattr +i  /usr/bin/do-release-upgrade
