Does the forum logs give an error when it crashes?
Do you have mongo and nginx logs on?
There should be some useful information in one of the logs as to what is happening.
When I go to my profile and click favorites I get this. It is not happening on my own site so I figure it is probably an issue with this site.

That worked. This was an issue with my cache.
@HolyPhoenix It's always the cache.
