What are these processes doing exactly --- can you show us the queries
they're executing? It might be worth attaching to a few of them with
gdb to get stack traces, to see if there's any commonality about the
traces:
$ gdb /path/to/postgres PID-of-backend
gdb> bt
gdb> quit
are you sure? y
$ <repeat with other backends, and/or same backend after a few sec>
