Mnesia stuck in transaction

Hello Mnesia experts,
I have a process hung with the following backtrace. What is the possible solution? This gen_server (workflow_manager_logs) is backed up with lot of messages delivered via RabbitMQ. Either I need a way to cancel this transaction or fix the database so that it will continue processing all messages.
Thanx,
