The FFFFFFFF in the store.log means the memory object was released.
Squid puts incoming objects into memory, swaps them out to disk, and the
if the object is larger than the tunable maximum_object_size_in_memory'
it releases the memory object. OS updates tend to be bigger than the 8
KB default for this.

Is there a SWAPOUT line for that same object?
