Hello there, I am running a FreeBSD/amd64 8-STABLE with GENERIC kernel as of February 17 on my box (quad core, 2 GB RAM), and recently I spot some interesting problems in my logs. My machine runs two instances of a client in two separate chroot environments in parallel with 32-bit and 64-bit userlands respectively, doing a nightly building and testing. According to the logs it puts a nice load on my system, though it still seems to be working fine. Except one thing: it produces strange error messages on swap space without an apparent reason (at least to me): xxx# tail -f /var/log/messages Apr 14 05:26:44 xxx kernel: swap_pager_getswapspace(4): failed Apr 14 05:26:44 xxx kernel: swap_pager_getswapspace(16): failed Apr 14 05:26:44 xxx kernel: Apr 14 05:26:44 xxx kernel: swap_pager_getswapspace(3): failed Apr 14 05:26:44 xxx kernel: swap_pager_getswapspace(16): failed Apr 14 05:26:44 xxx kernel: swap_pager_getswapspace(3): failed Apr 14 05:26:45 xxx kernel: swap_pager_getswapspace(16): failed Apr 14 05:26:45 xxx kernel: swap_pager_getswapspace(12): failed Apr 14 05:26:45 xxx kernel: swap_pager_getswapspace(2): failed Apr 14 05:26:45 xxx kernel: swap_pager_getswapspace(16): failed Apr 14 05:26:45 xxx kernel: swap_pager_getswapspace(16): failed Apr 14 05:26:45 xxx kernel: pid 7388 (throwto003), uid 1001, was killed: out of swap space Apr 14 05:26:45 xxx kernel: swap_pager_getswapspace(16): failed Apr 14 05:26:45 xxx kernel: swap_pager_getswapspace(8): failed Apr 14 05:26:45 xxx kernel: swap_pager_getswapspace(16): failed Apr 14 05:26:45 xxx kernel: swap_pager_getswapspace(16): failed Apr 14 05:26:45 xxx kernel: swap_pager_getswapspace(8): failed Apr 14 05:26:45 xxx kernel: swap_pager_getswapspace(16): failed Apr 14 05:26:45 xxx kernel: swap_pager_getswapspace(12): failed Apr 14 05:26:45 xxx kernel: swap_pager_getswapspace(9): failed Apr 14 05:26:45 xxx kernel: swap_pager_getswapspace(16): failed Apr 14 05:26:45 xxx kernel: swap_pager_getswapspace(9): failed Apr 14 05:26:45 xxx kernel: swap_pager_getswapspace(3): failed Apr 14 05:26:45 xxx kernel: swap_pager_getswapspace(16): failed Apr 14 05:26:45 xxx kernel: swap_pager_getswapspace(9): failed Apr 14 05:26:45 xxx kernel: swap_pager_getswapspace(3): failed ^C xxx# swapinfo -h Device 1K-blocks Used Avail Capacity /dev/ad0s1b 4194304 112M 3.9G 3% Do you have any ideas what might have happened?
