Bug ID: 106037
Summary: Libreoffice crash when LAN connected. Simple single
PC installation, without Samba, without network
drives.
Product: LibreOffice
Version: 5.1.4.2 release
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Calc
Assignee: libreoffice-bugs@lists.freedesktop.org
Reporter: matthewn...@yahoo.co.uk
New Shuttle XS pc, two screens (one HDMI, one 48 inch DP at 3840x2160 ultra).
Light Ubuntu 4.4.0-62-generic (x86_64), Threads CPU 4, UI Render default.
with ARandR to use both monitors.
LO Build ID 1:5.1.4-0ubuntu1.
Cancer research using five or six sheets, about twenty XY scatter plots, 150
rows, 150 columns per sheet approximately 8 Mb total. Wonderful! LibreOffice
is extraordinary and marvellous! Last year, one absolutely huge file was used
for number crunching in tens of thousands of rows and all but one of all
available columns. The quad core PC is only 2GHz, so at it's limits for
science, yet LO did the jobs, three hour calculation and 400 000 plots on a
scatter diagram. Simply amazing.
Progress is hampered with the more usual small files with multiple graphics as
Calc crashed every hour or so in 2016, particularly when changing a graphic
line or area colour transparency or moving a graphic on the sheet. Linux PC
restart is necessary (off - on). The LO recovery starts well, yet often offers
to repair a version of the document precisely two versions earlier than the one
that crashed. Accepting the offer causes messages about inadequate
permissions, inability to open, offer to save to a default folder. Once
running, it's possible to find the actual working document in "recently used"
and take things from there.
In 2017 it was noticed, just by luck, that a tablette on WiFi in the same
building using the same ADSL box for internet, lost access at precisely the
same moments as LibreOffice on the PC freezes (crash). The LO PC is cable LAN
(rarely used), no network drives, no Samba, yet is important when placing
research data from the Web on the HDMI screen and working it out on the DP
screen using Calc. It doesn't matter if an application for the internet is
opened or not and there are no applications with internet background activity,
no Skype, no email programs, nothing, just barebones for working. Only the
Ubuntu is known to look at the LAN for System Updates. One network printer is
used about once a month for ten minutes, yet otherwise stays off.
The hourly crashes was a very painful experience. In 2017,with the LAN cable
physically disconnected, all is useable and a huge relief. Early on, lower
video resolutions were tried and more memory allocated for Calc objects,
without changes to the Calc bugging, neither better nor worse. Single screen
without ARandR was tried. Same crashes, about every hour, yet can be after one
minute or one slide of the mouse.
It seems LO Calc may be stumbling into LAN memory space (or vice versa) or
colliding with Software Updates manager of Ubuntu. It's presumed that LO is
without internet needs nor online options such as spell checking with remote
dictionaries, yet I'm unfamiliar with it's full capacity. It's also presumed
that Lubuntu is without malware, keyboard loggers or any other data gathering
gadget. It's unknown why the LO PC crash would stress and distract the ADSL
modem router, rather than just drop off quietly without disturbing the router.
For the moment, the system is used stand-alone, LAN cable disconnected.
Ability to look at internet and use Calc simultaneously and stable would help
enormously.
Bug 99763 seems to discuss memory leak with similar effects, without the LAN
clue.
