Burak, i got something!! :) i'm running two wsgi processes for my wsgi application (via mod_wsgi). invalid result is always returned by first of them and valid result is always returned by the second (until i restart wsgi app). this is why every second request gets crazy (there's a 50% chance). now why is this happening ? some kind of desynchronization between processes ?
