Peter,
Here are some links to the threads I posted on LinuxQuestions.org about
this matter. The thread title is (in case you want to search for it
instead of logging into LinuxQuestions):
*Problem with the 4.4.75 kernel security upgrade dated 26 June 2017 (SSE
2017-177-01)*
https://www.linuxquestions.org/questions/slackware-14/problem-with-the-4-4-75-kernel-security-upgrade-dated-26-june-2017-sse-2017-177-01-a-4175610351/
And somehow this one got separated from the main thread:
https://www.linuxquestions.org/questions/slackware-14/problem-with-the-4-4-75-kernel-security-upgrade-dated-26-june-2017-sse-2017-177-01-a-4175610351/page2.html#post5771382
The fix, as stated in the response from "bormant" on the 08-07-17, 11:25
AM posting, is to add
"stack_guard_gap=6" to the LILO "append=" statement. If you are not
using Lilo, then this may look differently. The idea is to pass this
statement to the kernel when it boots. The second link is from a *buntu
user and has a link to a ubuntu answer to adding this argument to Grub,
the *buntu boot loader.

There is one caveat to this fix I should have mentioned in my first
response. The problem only shows up on 32-bit Linux, not 64-bit. So, if
you are running 64-bit Linux, this may not help. The alternate solution
would be to switch to 64-bit Linux, but then that could open up another
can of worms. I have been sticking to 32-bit because of the 32-bit apps
that I rely on.
I said it was technical.
HTH.

Generally I allow all updates that come through. How do I add the
kernal boot parameter? Is there any documentation that will guide me
through this process?

Peter,
What indication do you have that LO crashes?
Does it lock up or disappear (a hard crash)?
If the former, LO may just be taking a long time to process
something. Patience is a virtue. I have some reports that search on
database string fields that are quite slow to process the report. I
can go out and have a cup of coffee and maybe it will be done when I
return.
If the latter, there is a known security fix problem with Linux
kernels later than about 4.4.75 and Java. This problem affected
LibreOffice, but not OpenOffice, from my experience. There is a fix,
but it is technical, regarding stack frame gap size settings. The fix
is to add a kernel boot parameter to your booter (Lilo or Grub or
whatever). If you updated your *buntu since LO last worked, this may
be your problem.
HTH.

Base is installed and for my financial database the only problem I
have is reports. I followed the advice and installed the packages.
This made no difference. When I open the data base and select a
previously defined report the data bases crashes. If I use the
report creation facility when I select the report wizard again the
data base crashes.
Does base log these failures and if so where can I look at it?
My fishing data base opens but I cannot open fofms , tables ,
queries etc.
This problem with Base has occurred in the last 12 months.
Any suggestions on what to do next will be gratefully received.

I use Ubuntu 17.04 also, including the Libreoffice packages
installed directly from Ubuntu. The default install excludes Base,
and if you can't open a database, it seems like you don't have Base
installed. sudo apt install libreoffice-base should fix that,
For reports the packages you need are libreoffice-report-builder
and libreoffice-report-builder-bin. Use sudo apt install
libreoffice-report-builder* and they should install.

I reinstalled Libre Office Base from the Ubuntu repository. I

packages. a=There is nothing that I can find in the__Ubuntu
Software Repository that appears to relate to reports for
LibreBase. How can i find out what packages I have installed and
what packages are required forreports to work. I have an old data
base which has not been uses since January 2015 which I tried to
open today. This will no longer open for any thing , no forms or
views or tables can be opened.

Hi Peter,
Libre Base 1:5.1.6~rc2-0ubuntu1~xenial2
Ubuntu 16.4
When I first found the problem I removed LibreBase and
reinstalled it
but the problem with reportsremained the same.
This is a special Ubuntu-version of LO. Have a look into your
packagemanager. Did you install all packages for the
libreoffice-report-builder? Have heard there isn't only one package,
which should be installed for reports with the Ubuntu-version of LO.
Regards
Robert
