I use a c program based on the libevent2 only, verified that the memory issues was caused by the libcouchbase. It has no problem to talked to the couchbase server correctly either chunked or not. Another suggestion for the api is that normally, for the libevent2, the error callback need to stop the event loop. But in the libcouch base, this is not possible because the io definition is hidden as internal. It it better for the libcouchbase to stay same as libevent2, but hide all the smart vbucket logic internally
