This bug concerns about having external linked data and shared mode.
Steps to Reproduce:
1. create an .ods document in Calc
2. add name to cell blocks (https://help.libreoffice.org/Calc/Naming_Cells)
3. add new sheet
4. link named cell block as external data to new sheet (https://help.libreoffice.org/Calc/Link_to_External_Data)
5. save document
6. share the document (Tools->Share spreadsheet) and save it
7. try to open the document in another computer over shared folder, I used Virtualbox 5.2.20 (extension pack + guest additions installed) shared folder
8. there will be a warning message "Automatic update of external links has been disabled" in both side and an option to click the button "Enable Content" - I clicked that in both side
9. After opening same shared document in two different locations: one locally, another over network - at some point the LibreOffice will start using CPU close to maximum (96...98%) and will crash - window keeps open but not responsive and trying to interact with that, system asks that this does not respond, would I like to close that using force. So I will close it with force.
There is a warning "Automatic update of external links has been disabled" when opening file with linked data in shared mode. LibreOffice Calc will start consuming CPU intensively and will finally crash.
LibreOffice Calc will not crash. If external linked data is not supported while shared mode enabled then either external data linking should be forcibly turned off with appropriate warning or not allow to use shared mode while external data linking is active. If supports then such warning should not be displayed and data linking should work as promised.
User Profile Reset: No
Used 64-bit AppImage version of LibreOffice in Linux Mint 19 MATE (both: host and guest in terms of VirtualBox)
Noticed also https://ask.libreoffice.org/en/question/162708/automatic-update-of-external-links-has-been-disabled/ but this issue seems to be not connected with that setting whether updating links are updating automatically or not.
Also wanted to mention that when such situation occur where .ods with externally linked data and shared mode is open and trying to unshare then it will not work - still remains shared. Deleting the external data linking from Edit->Links to external files... and then unsharing but still it will not turn off the sharing (next to filename in title bar still (shared) is written). But when hitting to Save then it says "This spreadsheet is no longer in shared mode" and only choice is OK and it asks to save under new name but I would like to not create yet another file but just turn off sharing and/or also linking if needed. Actually by turning off the sharing should be enough. But it seems that once the sharing is enabled while external data linking is enabled, it breaks something and there seems to be no way back to turn off sharing anymore.
The last information after some testing is that even the sharing plays no role. While added linked data to same sheet where named cell block locates, saved document and when reopening - it says a warning message "Automatic update of external links has been disabled" regardless of Tools->Options->LibreOffice Calc->General->Update links when opening->Always (from trusted locations)
I am having the problem with 22.214.171.124
I was using 126.96.36.199 without the problem. I had previously tried 188.8.131.52 and had to go back to 5 for other reasons. Don't remember haing the problem on 184.108.40.206
It also fails in safe mode for me.

I could not repro. Used the Virtualbox shared folder method. Linux host, Win 10 guest. LibO 6.2.0 in both. Named range was simple, 3 cells with numbers. After an hour, CPU remained at 0% in both instances.
A trace of the crash would be nice. Edmund, Rich: neither of you sent a crash report? Alternatively: https://wiki.documentfoundation.org/QA/BugReport/Debug_Information
My bad, perhaps I should have opened a new bug as mine is not the same as the OP describes. Mine seems the same as reported in Ask LibreOffice
with the title "Automatic update of external links has been disabled" several people reported this problem even though Tools/Options/LO Calc/General/Always
Although I get the message in a yellow bar at the top of the spreadsheet that says
""Automatic update of external links has been disabled" I do not get high CPU and crash.
I have created two simple files/spreadsheets that fail. 1_test.ods and 2_test.ods In file 2_test.ods I have cell a1 with an external link to cell a1 in 1_test.ods
This fails when I open 2_test.ods. Unfortunately you cannot test this directly as you do not have the same paths for the external link. But if you recreate the link it should fail.
Meanwhile I will readup on your link to debug information and will add what I can do.
Created attachment 149390 [details]
two test files and GDBtrace
Created attachment 149391 [details]
1 test file
Created attachment 149392 [details]
2nd test file
A description of how I created the trace.
from terminal: libreoffice6.2 --backtrace
Then load file 2_test.ods
After seeing the "Automatic update of external links has been disabled" message I then entered from another terminal: pkill -15 soffice.bin

I'm sorry, but the backtraces should have been taken of an actual crash. I will mark them as obsolete so they will not confuse anyone.
I repro the problem of the Automatic update question appearing regardless of the setting.
1. Tools - Options - LibreOffice - Security: Macro security - Trusted sources
2. Add the location of your spreadsheet with external link to the Trusted File Locations
3. Tools - Options - LibreOffice Calc - General - Update links when opening: change to Always (from trusted locations)

Having same problem in windows 10 Version 1809 build 17763.316.
Links to external spreadsheets works fine in LO 220.127.116.11, but fails after update to LO 6.1.5, also tried LO 6.2.0 which fails. Gone back to 18.104.22.168 to be able to work.
Bibisected the prompting even when dir in Trusted locations and updating set to "Always" with win32-5.1 repo to https://gerrit.libreoffice.org/plugins/gitiles/core/+/77cc71476bae2b3655102e2c29d36af40a393201%5E!/
LinkUpdateMode is a global setting
Adding Cc: to Stephan Bergmann
Note to Stephan: the talk of crashing, sharing of spreadsheet in the beginning of this report is a red herring. A simple test case is having a target sheet with named range and the file that links to the target. Then using the steps in comment 13.
Stephan: argh, I am sorry: Tools - Share spreadsheet is a required step after all!

(Apparently, this needs to be done for the document containing the link (2_test.ods), not the linked-to document (1_test.ods), when going with the attachments from comment 9 and comment 10.)
The reason for the "Automatic update of external links has been disabled. [Enable Content]" info bar is that the actually opened document is apparently a temporary copy (some <file:///tmp/lulmhoxl.tmp/0.ods> in my case), so that SvtSecurityOptions::isTrustedLocationUriForUpdatingLinks (unotools/source/config/securityoptions.cxx, introduced with <https://gerrit.libreoffice.org/plugins/gitiles/core/+/77cc71476bae2b3655102e2c29d36af40a393201%5E!/> "LinkUpdateMode is a global setting") returns false.
Maybe one of the Calc developers (now on CC) has an idea what should actually happen here?
AFAIK there's no automatic "if this is a temporary copy because of a shared document then use the original path instead of the path of the copy" fallback for such case.
There's SfxObjectShell::IsDocShared() and SfxObjectShell::GetSharedFileURL() which ScDocShell inherits and sounds about right to use in calls to SvtSecurityOptions::isTrustedLocationUriForUpdatingLinks() (or a second call if the original call fails and IsDocShared()?)
Stephan Bergmann committed a patch related to this issue.
It has been pushed to "master":
tdf#120736: For Calc shared documents also check the original document URL
It will be available in 6.3.0.
The patch should be included in the daily builds available at
https://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More

Affected users are encouraged to test the fix and report feedback.
Seems to be working now, thanks!
