when there is no space on the drive where /tmp resides, users get verification mismatch all the time.

i wouldn't say this is an error in ochiba per se, but i thought you should know :)

Weird!

I was baffled at first, but now I think I know why. The verification code uses a PHP session. Session files are usually stored in /tmp (typically sess_092j3kl2lk34092j34lkj or whatever).

So, there's nothing too worthwhile doing in ochiba about it :).
