Thank you Joseph Engo~ I am still working on this issue and found something new.
If file is used for PHP session storage, it has a lock, which keeps the data form be damaged while simultaneously operations. But for memcached, it has not a similar mechanism to protect the data (or memcached is not thread safe?), so the value will be overridden. I don't know if this is right, anyone can help?
