I'm hoping somebody has seen this before, as I'm trying to nail down which change caused this. My old setup was stable. I ended up doing 3 things: - Moved from vanilla FreeBSD to HardenedBSD - Added a slave server - Moved nsd from 127.0.0.1 to a virtual IP because of the slave server (unbound is on the 'main' IP) Everything works for a while, and then both the master and slave eventually die with the same error (but not exactly at the same time): Jul 6 06:59:14 xxx nsd[93796]: mmap(/tmp/nsd-xfr-93796/nsd.93796.task.0, size 576) error Invalid argument Jul 6 06:59:14 xxx nsd[93796]: tasklist: out of space, cannot add applyxfr Jul 6 06:59:14 xxx nsd[27023]: signal received, shutting down... Jul 6 06:59:14 xxx kernel: [791683] pid 93796 (nsd), uid 216: exited on signal 11 I guessed maybe it was the memorylocked setting in /etc/login.conf, so I tried doubling that, but that didn't seem to do it. Any ideas? Thanks! -Dustin
