Thanks Seyeong for the quick patch rework to include the second upstream
commit.
The trusty debdiff has been uploaded in the Trusty upload queue, now
waiting for SRU verification team approval in order to start building in
trusty-proposed.

right,
In my test, only 7a2e247 commit fixes this symptom.
but
I think be45099 is worth SRUing with 7a2e247 as commit's description
5a11a1d is quite far
uploaded debdiff for two patches.
Thanks

[ STS SPONSOR REVIEW ]
@Seyeong,
According to your dediff you are only cherry-picking "7a2e247 bugfix:
plug a memleak in imuxsock".
This commit has been introduced upstream starting with
"v7.6.3-158-g7a2e247", thus it seems like this bug is only affecting
Trusty as you previously mentioned.

I can confirm this bug still exists on ubuntu 14.04.4
It only seems to happen to CRON entries although the github bugreport
referenced in #14 confirms the problem is with rsyslog.
Supposedly setting '$RepeatedMsgReduction off' in /etc/rsyslog.conf should work
around this problem.

I found a matching bugreport on the rsyslog issuetracker at github. The
report is about ubuntu 14.04.1 too.

I'm seeing the same behavior out of rsyslogd. It shows up most
frequently with CRON runs, but I've seen it on kernel syslog entries as
well.
I'm shipping my logs into ELK, and I was noticing that old indices kept
getting updated. When I dug into the issue, I saw that this was
happening on a rela
I don't get to anything meaningful before the weekend. Gosh, it's at
least 10 years since I last straced anything - have to read up on that
too.
Jup, I'm using rsyslog. I'll keep an eye on xconsole stuff but IIRC I
disabled that in rsyslogd.conf.

Hi Stefan,
yup yup, same here, only showing for cron related entries in syslog.
Also somewhat busy due to a noisy sogo/postfix/openchange/dovecot plus
all sorts of extra add-ons. Not nearly as noisy as a firewall logging of
course ;-)
Can you strace your cron pid for a bit, including forks and ho
Hi,
did you notice that I wrote that the time jumps ONLY affect CRON
entries? No other message shows them, even not the firewall log which
receives logs from a Cisco ASA in debug logging mode, so there's A LOT
of logs coming in on that channel.

I'm convinced this is more rsyslog related and not cron.

Title:
Unexplainable time jumps
Figured I'd give it a quick google for this weirdness and stumbled upon
this report. Confirmed it, but then started doubting if it actually is
cron that's causing this weirdness. So I put a simple strace on my
freshly restarted cron with strace -f -p -s 1000 2>&1 | grep
'CRON\[' and left this run

One of the mentioned network devices is a Firewall which logs verbosely,
i.e. there is a LOT of logs coming in from there and /var/log/firewall

Forgot: Restarting CRON does not solve the problem. Rebooting the system
