yes, I have seen this before when I used mysql. we had a short discussion on it recently. it looks like concurrency problem (the guess on my side), but access to the DB should be per thread.
no solution. in my case it was on rails startup where there were some DB access in the init scripts (for configurations). so I could work around it with a "retry" or so. so that is all I can tell you and I never saw with sqlite3 or postgres !!! -- You received this message because you are subscribed to the Google Groups "DataMapper" group.
