Okay, after further digging I have excluded any issues with SELinux preventing caching. There have been no SELinux denials at all in the last three days so this issue is going to be in the code base. There are few things in life as enjoyable as hunting down a memory leak. Please note the heavy sarcasm :).

Update:

Okay, The function copyToString() in the Util.php allows the buffer to be read indefinitely or until it reaches an eof(). This only happens if the $maxLen variable is -1, which happens to be its default value. Because we end up in the body of this if() we know that either -1 was passed or the default value was used.

So apparently a file larger than 8gb was served up? That seems extreme though I have raised the bar to 12gb and waiting to see if that fails in time.

This seems reckless as a lot of servers may not have 8gb+ to offer up. This looks dubious and certainly a work around can be reached.
