<div dir="ltr">I think you should check again, I believe you have made a mistake. You will only get this error and see that output if you have a mnesia.beam on the code path that is not the one that ships with Erlang. Having only a setup/0 export makes it extremely likely that this is the original mnesia.beam that would be produced from the mnesia.erl that you pasted earlier in this thread.<div>
<br></div><div>Try evaluating code:which(mnesia). If it doesn't show the same directory as code:which(mnesia_locker) then you will know which beam file to delete.</div></div><div class="gmail_extra"><br><br><div class="gmail_quote">
