So, you have a cluster of three nodes, and they share several Mnesia
tables, that (obviously) synchronize often.

The only thing I could get from that report is: it seems a process
that is somehow related to pubsub, is later reported to consume too
much memory when is executing a function called
mnesia_tm:async_send_dirty/6. Maybe that 'send' means send to another
node in the cluster.
