I'm happy to upload this fix to Trusty and Utopic but we will need a
test case in the bug description so that the fix can be verified. Could
somebody please provide one following the example at
http://wiki.ubuntu.com/StableReleaseUpdates? Thanks!

7.4.4-1ubuntu2.1 makes rsyslogd to take all the CPU in OpenVZ

Bug description:
After updating rsyslog from 7.4.4-1ubuntu2 to 7.4.4-1ubuntu2.1 the rsyslogd
process started to take all the CPU on my machine.
The modification made by this release is described in #1274444, it is the
activation of KLogPermitNonKernelFacility option.
I don't know exactly the effect of this option but it seems to have a
permanent effect : even after downgrading the package or manually removing the
option from /etc/rsyslog.conf the issue remains.
My syslog is full of :
Sep 8 10:28:40 sentry rsyslogd: imklog: error reading kernel log - shutting
down: Bad file descriptor
Sep 8 10:28:40 sentry rsyslogd: message repeated 498 times: [imklog: error
reading kernel log - shutting down: Bad file descriptor]
Sep 8 10:28:46 sentry rsyslogd-2177: rsyslogd[internal_messages]: 519517
messages lost due to rate-limiting
I guess this is what causes the CPU load.
I am running Ubuntu 14.04.1 LTS in an OpenVZ container on Proxmox 3.2. The
kernel is 2.6.32-28-pve
