Reduce your code down to the smallest possible test case that fails and then post it here. Without seeing the code, we have no way of knowing what is going on. Also, you can try turning on trace().

DBI->trace($trace_level, $trace_filename);

See the docs for more information about that. It can help you solve most DBI problems.
