Yes, when memory runs full, memory is cleared.

OK, does APCU have no elimination algorithm? If the cache is full, it will have some impact on the system.

It does have garbage collection and removes expired entries, but the heap may be fragmented and it may be unable to allocate a large enough region, or there may simply be too much data. (it doesn't seem like it will move heap entries)

When it can't allocate a large enough continuous block for the data it'll clear memory.

Switching to a smaller serialization format such as igbinary/msgpack or allocating more shared memory can help make this less likely
