I don't know what 'pop' is in this context, but is its accessor
thread safe?  Have you got a Mutex around it so that only one thread
fiddles with it at once?  Similarly for the site array.  I suspect
that could do odd things to memory.

Depending on what check does with this data, I'd expect lots of
memory to be used, then.
