Sorry for the slow response. Yes, mmaped files cause segfaults on IO. Not much we can do about this without kernel changes. *** Bug 1177726 has been marked as a duplicate of this bug. *** *** Bug 1164427 has been marked as a duplicate of this bug. *** *** Bug 1151848 has been marked as a duplicate of this bug. *** *** Bug 1098722 has been marked as a duplicate of this bug. *** I now added some code to journald git, that catches SIGBUS, remaps the triggering page to an anonymous page, then detects this afterwards and rotates the file away. This should make us more robust on file systems where overwriting bytes in a file can fail due to disk full, such as COW file systems (btrfs). *** Bug 1053292 has been marked as a duplicate of this bug. *** http://cgit.freedesktop.org/systemd/systemd/commit/?id=fa6ac76083b8ffc1309876459f54f9f0e2843731 This patch is nontrivial to backport, even to F20. |
