One of the things that will trigger errors and cause problems for the host is if you have Live Traffic View enabled. It even says in the Wordfence instructions:

On most servers that have sufficient resources, Live Traffic in Wordfence works flawlessly. In fact, we enable Live Traffic on our own production servers which receive a significant amount of web traffic. However, if you are using a low cost hosting plan that severely limits the resources you have available, you may consider disabling live traffic to reduce the load on your web server.

See when I set Wordfence up I didn't enable Live Traffic View. Like I said I've been using the free version of it for almost 2 years and never had any problems.
