Bug description:
I've hit this problem while testing juju charms that use ntp
(specifically hbase - bug 800708).
The first instance in the first LXC container start OK; however
subsequent instances in other LXC containers fail as ntp is installed:
root 1157 416 0 14:48 ? 00:00:00 /usr/bin/dpkg --status-fd 49
--configure resolvconf:all openjdk-6-jre-headless:amd
root 1313 1 0 14:48 ? 00:00:00 /usr/sbin/libvirtd -d
root 1398 1157 0 14:48 ? 00:00:00 /bin/sh
/var/lib/dpkg/info/ntp.postinst configure
root 1437 1398 0 14:48 ? 00:00:00 /bin/sh /usr/sbin/invoke-rc.d
ntp start
root 1453 1437 0 14:48 ? 00:00:00 /bin/sh /etc/init.d/ntp start
root 1458 1453 0 14:48 ? 00:00:00 lockfile-create
/var/lock/ntpdate
Running lockfile-create by hand after killing the hanging lockfile-
create:
ubuntu@jamespage-hendrix-hbase-regioncluster-2:~$ lockfile-create
/var/lock/ntpdate
*** glibc detected *** lockfile-create: malloc(): memory corruption (fast):
0x000000000105b0e0 ***
[Test Case]
Set a hostname of 64 characters (HOST_NAME_MAX is 64) and create a lock file:
$ lock=/var/lock/lockfile-create-test
$ lockfile-remove $lock
$ sudo hostname hostna01234567890123456789012345678901234567890123456789
$ lockfile-create $lock
