If you're using Apache with the prefork MPM (apache2ctl -M | grep mpm should tell you what you're using), you probably need to lower your MaxClients setting. The link will lead you to older posts in the forum on this topic which should help you choose a suitable value.

The whoopsie daemon is nothing more than a waste of memory and CPU unless you have configured it to send crash reports to Canonical. You can remove it with apt-get purge whoopsie.

You are running both PostgreSQL and MySQL. Do you have a specific need to run two different database servers? If not, I would eliminate one of them.

Doing these things will reduce the memory demand on your server and the chances that it will run out of memory in the future.

Thanks Vance. Reducing MaxClients really seems to have done the trick.
