Hello Kevin, I don't want to step on Colin's toes here, but I couldn't sort out anything from the logs or files so far. I've had success before with perf to grab call graph information. The usual process is along the lines of:
- enable the ddebs.ubuntu.com repository to get access to debug symbols: https://wiki.ubuntu.com/Debug%20Symbol%20Packages - install packages openssh-server-dbgsym libc6-dbgsym .. as needed - Record perf results during testing with something like: sudo perf record -e syscalls:sys_enter_socket -R -a --call-graph dwarf sleep 20 - test - Check results with something like: sudo perf script With luck this will spit out the function names of the call chain at the time of the socket() syscall that is being killed (probably alongside a lot of unrelated instances -- it's possible to tune the perf line to narrow it down if necessary). I hope this helps, Thanks -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1690485 Title: openssh-server SIGSYS with 'UsePrivilegeSeparation sandbox' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1690485/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
