I have looked at a series of memcached_set, memcached_get, memcached_delete, memcached_flush. I'm getting strange return values, followed by a client stuck in a poll.
Everything goes quite well for a while. Then the return codes get strange, with memcached_set returning NOT_FOUND, memcached_get returning stored. Other strange errors, and eventually the client is stuck in a poll. I assume that the client and server disagree about their position. Once they get lost, things get worse over time. This is on a FreeBSD4.11 box, with a 1.2.4 server, and a new version of libmemcached, pulled down yesterday. A few weeks old version also shows this problem. What should I do? Perhaps I should should repeat the request. Perhaps I should shut down and reopen the connection. If it doesn't happen often, I may try this. Perhaps I should try to understand the problem more completely. Here are a few odd returns which I see. Then things get stranger. memcached_get returns MEMCACHED_STORED. In fact, it returns quite a few of them. Eventually memcached_set returns a few MEMCACHED_SERVER_END, mingled in with the MEMCACHED_STORED. memcached_set returns NOT_FOUND. memcached_get returns SERVER DELETE memcached_set returns SERVER_END memcached_set returns NOT_FOUND
