In chasing down this problem, I stumbled upon something of moment: the
problem does NOT seem to happen with kernel 3.13.
Some weeks back, in the hope of getting past another problem wherein the
root filesystem "becomes" R/O, I upgraded from 3.13 to 3.19 (Ubuntu 14.04
LTS). The kernel upgrade was done as shown here (there's some extra stuff
to get rid of Ubuntu desktop and liberate some disk space):
apt-get update
apt-get -y remove unbuntu-desktop
apt-get -y purge lightdm
rm -Rf /var/lib/lightdm-data
apt-get -y remove --purge libreoffice-core
apt-get -y remove --purge libreoffice-common
echo " Installing new kernel"
apt-get -y install linux-generic-lts-vivid
apt-get -y autoremove linux-image-3.13.0-32-generic
apt-get -y autoremove linux-image-3.13.0-71-generic
update-grub
reboot
After the reboot, a "uname -r" shows kernel 3.19.0-42-generic.
Under this kernel I can now reliably reproduce the failure to stop a
MongoDB container. Specifically, any & all attempts to kill the container,
e.g.,via
Marathon HTTP Delete (which leads to docker-mesos-executor presenting
"docker stop" command)
Getting inside the running container shell and issuing "kill" or
db.shutDown()
causes the mongod container
- to show in its log that it's shutting down normally
- to enter a 100% CPU loop
- to become unkillable (only reboot "fixes" things)
Note finally that my conclusion about kernel 3.13 "working" is at present a
weak induction. But I do know that when I reverted to that kernel I could,
at least once, stop the containers w/o any problems; whereas at 3.19 I can
reliably reproduce the problem. I will try to make this induction stronger
as the day wears on.
Did I do something "wrong" in my kernel upgrade steps?
Is anyone aware of such an issue in 3.19 or of work done post-3.13 in the
area of task termination & signal handling?
Thanks for your help.
