You have been subscribed to a public bug by Robie Basak (racb): We have 1 server (among hundreds) that its ntp service is crashing.
A few minute/seconds after a start attempts we can see the following in syslog: ntpd[2729]: peers refreshed ntpd[2729]: Listening on routing socket on fd #49 for interface updates ntpd[2729]: i/o error on routing socket No buffer space available - disabling kernel: [157516.495224] ntpd[2729]: segfault at 31 ip 0000000000000031 sp 00007ffff9f11788 error 14 in libpthread-2.15.so[7f967a5d9000+18000] OS: Ubuntu 12.04.4 LTS Kernel: 3.11.0-19-generic I tried to compare it to other servers, and the only thing I could find that is different is that while it's up (before it crashes) I can see the following when running "lsof | grep ntp": ntpd 2729 ntp 49u sock 0,7 0t0 2473952565 can't identify protocol. ** Affects: ntp (Ubuntu) Importance: Low Assignee: Eric Desrochers (eric-desrochers-z) Status: Confirmed ** Affects: ntp (Ubuntu Precise) Importance: Undecided Status: New ** Affects: ntp (Ubuntu Trusty) Importance: Undecided Assignee: Eric Desrochers (eric-desrochers-z) Status: Confirmed ** Affects: ntp (Ubuntu Vivid) Importance: Undecided Status: New ** Affects: ntp (Ubuntu Wily) Importance: Low Assignee: Eric Desrochers (eric-desrochers-z) Status: Confirmed -- NTP : Use-after-free in routing socket code after dropping root https://bugs.launchpad.net/bugs/1481388 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to the bug report. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
