Same memory leak here, running kvm+libvirtd+multipath-tools on nodes with SAN access over QLogic cards However i noticed something which i guess is highly related:
udev is constantly "discovering" the 4 multipath devices (sdb/sdc/sdd/sde) and causing a high CPU load of around 3 (8 CPU system). "ps" shows a process tree like this again and again 393 ? S<s 22:09 udevd --daemon 20696 ? S< 0:12 \_ udevd --daemon 7171 ? S< 0:00 | \_ /sbin/multipath -v0 /dev/sdb 7190 ? R< 0:00 | \_ /sbin/mpath_prio_emc /dev/sdd 20702 ? S< 0:10 \_ udevd --daemon 7177 ? S< 0:00 | \_ /sbin/multipath -v0 /dev/sdc 7189 ? R< 0:00 | \_ /lib/udev/scsi_id -g -u -d /dev/sdb 31869 ? S< 0:01 \_ udevd --daemon 7179 ? S< 0:00 | \_ /sbin/multipath -v0 /dev/sdd 7191 ? R< 0:00 | \_ /sbin/mpath_prio_emc /dev/sdb 31875 ? S< 0:01 \_ udevd --daemon (PIDs change all the time, they are really being called anew). Uploading the output of 2-3 seconds of "udevadm monitor -e" -- multipath + libvirtd eats away more memory over time https://bugs.launchpad.net/bugs/571093 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
