Fair point. > What OS, OS version, and filesystem? Up-to-date RHEL6 (kernel 2.6.32-754.12.1.el6.x86_64), ext4 over LVM on spinning rust with an LSI MegaRAID controller in front of it. Since complaining, I've done half a dozen more parallel check-worlds without issue, so the error was and still is rare. This matches the fact that we've not seen it in the buildfarm :-(. regards, tom lane
