https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=204426 --- Comment #11 from rblayzor@inoc.net --- Since we're using a FreeBSD diskless boot and NFS_ROOT I normally buildworld (and kernel) from sources and install in a new NFS_ROOT path, then boot the diskless servers with the new root path. Before booting however, I will also force rebuild (portupgrade -af) everything against the new version of FreeBSD (kernel/userland, libs, etc). So the binaries that are crashing *are* being rebuilt under FreeBSD 10.2. We never experienced this in 10.1 and in fact, we even rolled back and booted one of the diskless servers using an old NFS_ROOT path with 10.1 (same versions of Exim and Dovecot) and those have not crashed. Usually I will experience these types of seg faults on every VM server at least once a week. (currently these servers are lightly loaded because of this issue). Normally I would have no problem believing this is an application but since it does not appear to happen on 10.1 and only on 10.2, coupled with the fact I'm seeing similar crashes on two different applications that were otherwise running fine is very suspect. The applications are compiled with debugging symbols, but the crash always happens in a system library. I've contacted both Dovecot and Exim teams on these crashes and both agreed that it seemed to be some type of system library issue. I'm not ruling out that it may be something with our install, but it's fairly straight forward FreeBSD diskless install. Running out of places to look. -- You are receiving this mail because: You are the assignee for the bug.
