Public bug reported:
Hello,
after running updates today to linux-
image-4.4.0-127-generic_4.4.0-127.153 and rebooting i noticed that iotop
is not working any more. Reason are empty lines in /proc/PID/status,
which confuse iotop (and me)
In new view there is an empy line between Seccomp and
Specu
yes, i can fix this in iotop, but i thin the main problem is kernel and
there should not exist an empty line under /proc/PID/status
Ubuntu Kernel Bot told me to send logs, but i cant run apport-collect
for security/dataprotection reasons.
Thanks

Hello,
i installed v4.17-rc6 and this problem seems fixed, no emtpy line in
/proc/PID/status, but i also miss the line Speculation_Store_Bypass which was
existing in 4.4.0-127-generic #153-Ubuntu
So may be this is fixed because meltdown/spectre patches are not applied? Iam
not sure, so i hesita

When this new kernel will be released? This bug is killing our MySQL
Servers. Booting old kernels is only a bad workaround. I think a lot of
people with busy servers will have a problem.
This is 2.nd time we were hit by a big bug within short time. In oct 2016 our
nameservers got problems because
When this fix will appear in official kernel-release?
Yesterday i updated Trusty Tahr/14.04 to 3.13.0-103-generic and this problem is
still present.
This is a problem for all people who use 14.04 in high frequented environments,
just like nameservers.

Setting net.ipv4.neigh.default.gc_thresh1/2/3 on 3.13.0-97.
I also upgraded to 3.13.0-106-generic from canonical-kernel-team ppa and
can confirm it is working again:
# sysctl -w net.ipv4.neigh.default.gc_thresh1=8192
net.ipv4.neigh.default.gc_thresh1 = 8192

Our servers are not connected with public internet. i cant run apport-
collect:
ERROR: connecting to Launchpad failed: [Errno 110] Connection timed out
You can reset the credentials by removing the file
"/root/.cache/apport/launchpad.credentials"
Today Morning same notice like yesterday. Again
I collected some more loglines, produced by unproductive member of a
haproxy failoversystem with usually zero load. over the weekend there
are affected several servers. I think this is serious.

Sep 8 17:01
It seems that Ubuntu 22.04 is affected in a critical way. Currently we had
freezes only on Ubuntu22, but in Ubuntu 20.04 there are similiar loglines.
After some hours of running the ubuntu 22.04 crashes and kernel/systemd are
damaged.

I did found a workaround, but iam still convinced that we have a kind of bug.
I think i should explain our typical systemsetup, for better understandig.
Typical field of application are failoversystems. overall we use very few
software and systems have minimal load.
we have 2 servers in a cluste
