            Bug ID: 131749
           Summary: When updating external references to websites within
                    libreoffice calc, the process uses all memory, until
                    the operating system kills it.
           Product: LibreOffice
           Version: 6.4.2.2 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: ralf.fehlau at gmx.net

Description:
An ods file with external links consumes all memory during update. Libreoffice
uses about 12 GiB of RAM during 3 Minutes of cpu time. Thereafter, the
operating  system kills libreoffice.

I cannot attach the file, because there are a lot of private data in it. There
was another case in the past regarding the same problem. See case #88006

While investigating the origin of the problem, I observed, that there are
several links where LO could not fetch any data, e.g.
https://kurse.boerse.ard.de/ard/kurse_einzelkurs_uebersicht.htn?i=115061 . When
I update this link manually, the first try returns an error, the second try is
successful.

Steps to Reproduce:
1. Open ods file with references to external data (links to web content),
2. click on the button allow update ("Aktualisierung zulassen" in german)
3. wait until all memory is occupied

Actual Results:
libreoffice is killed by the operating system, LO calc is unuseable.

Expected Results:
all web content is updated


Reproducible: Always


User Profile Reset: Yes
