If it was hitting everyone, all the machines in the world would be going oom during the nightly updatedb run. Can you try a different compiler version? And try disabling any "unusual" config options, such as filesystem quotas, extended attributes, etc? Can you narrow the onset of the problem down to any particular kernel snapshot? Try disabling laptop_mode, if it's set. Carefully review the logs for any oopses: oopsing while holding shrinker_sem will do this for sure.
