A closely related problem is being spontaneously logged out if you didn't select the "remember me" checkbox when you logged in.
Strangely, this only happened in the Thai wikipedia yesterday, while in the english one the login was remembered at the same time.
It's not that strange, assuming it is a memcached server problem, the frequency of the problem would depend on which server your session ID is on, and you have a different session ID for th and en. That's why logging out and logging back in helps: you get a different session ID, hopefully on a different server.
