6.4.* didn't really have any check/defense against spawning more
backends than it had resources for. 6.5 does check and enforce the
maxbackends limit. It's certainly possible that Matthew's running into
some kind of resource-exhaustion problem, but I doubt that it's just
the number of backends that's at issue, except indirectly. (He could
be running out of swap space or filetable slots, possibly.)
