Locking Up / Not Responding / 500 Error

The 930MB limit is in Wincache....however, Wincache is still just a guest in PHP's process, which is just a guest of the OS. I'm not sure whether this limit is imposed by PHP or by the OS, but either way, Wincache is making a call to alloc something big,
and PHP is saying, "No."
I just looked through the implementation of wincache_ucache_info, and if you supply a $key, then Wincache will only fetch that one element. So you shouldn't be trying to alloc the whole array in that case.
Looking at your code, if $key is null, it looks like the wincache_ucache_info() function will try to get the whole cache. Is the code that's calling
getAgeOfEntryInSeconds() guaranteeing that $key is non-null in all cases? You might consider adding an assert that $key
is non-null. Otherwise you run the risk of unknowingly hitting this alloc failure.
