Title:
memory leak with unknown reason after upgrade to utopic
Status in linux package in Ubuntu:
Confirmed
Bug description:
I'm not sure if this is the right component/package. We are not able
to identify a package/program which could be responsible for this bug,
so we assume it is the kernel or at least a kernel configuration.
Since the upgrade from trusty to utopic at October 27., our three
servers for package building are massively swapping. This leads to by
a factor of four slower build times. There were no configuration
changes at all.
Munin graphs of one of the affected servers are attached.
The system has 48GB memory, and we have configured several ramdisks:
root@cx1000-02:~# mount | grep -E "tmpfs|ramfs"
none on /sys/fs/cgroup type tmpfs (rw,uid=0,gid=0,mode=0755,size=1024)
udev on /dev type devtmpfs (rw,mode=0755)
tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755)
none on /run/lock type tmpfs (rw,nodev,noexec,nosuid,size=5242880)
none on /run/shm type tmpfs (rw,nosuid,nodev)
none on /run/user type tmpfs (rw,nodev,noexec,nosuid,size=104857600,mode=0755)
tmpfs on /var/tmp/obs type tmpfs (rw,size=36G)
tmpfs on /run/obs type tmpfs (rw,relatime,size=1G)
ramfs on /var/obscache type ramfs (rw)
tmpfs on /run/obs type tmpfs (rw,relatime,size=1048576k)
The build service uses several chroot environments to build packages
for several distributions (http://openbuildservice.org/).
You don't see any process which allocates so much memory with 'top'.
Even after stopping the build service and unmounting /var/tmp/obs you
are not able to deactivate the swap via swapoff -a:
root@cx1000-02:~# swapoff -a
swapoff: /dev/sda5: swapoff failed: Cannot allocate memory
We also tested the latest kernel (3.16.0-28) and an old trusty kernel
(3.13.0-40) without success. Also patching perl to exclude the perl
bug https://rt.perl.org/Public/Bug/Display.html?id=123198 as root
cause doesn't help.
We don't have any idea what's the cause for this problem...
We can deploy debug packages or anything else on the system, so please
hesitate to ask for any information or help.
