The postgres segment looks pretty standard here. I'm a bit curious what all the lapham-owned destroyed segments are --- any idea? Although it seems that they can't possibly be relevant. I'm kind of leaning to the idea that we're seeing the results of some corner-case kernel bug here. Anyone familiar with what part of the Linux kernel implements shmctl()? I've never dug into it ... regards, tom lane
