            Bug ID: 82547
          Assignee: libreoffice-bugs@lists.freedesktop.org
           Summary: Main drop down menu freezes libreoffice and whole
                    system
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: lee.fi...@gmail.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: 4.3.0.4 release
         Component: UI
           Product: LibreOffice

Yesterday worked round a system freeze problem on libreoffice

system: xubuntu 14.04 (all patches/updates applied) x64
graphics: amd (tried 2 different cards cards)
processor: core 2 duo (dell 745)
ram: 3gb

Cause: seems to be recent documents list.
Temp Resolution:  clear the recent documents list (did via an extension)

Other Info: most of recent documents located on samba over a vpn, vpn was
active and responsive. (openvpn xubuntu stock)

Libreoffice versions tested:  4.2 (xubuntu repo) and 4.3 from the fresh ppa.


Description:

Open a libreoffice app (i tried calc and writer), do some typing on the doc or
in a  cell, all seems fine.

As soon as you click a menu item be it Help, Tools, Edit or File etc, the
system locks / freezes for a long period of time (maybe a minute or more).  You
cannot tab between applications, or move between apps using the mouse.  Mouse
pointer does move around the screen.

I recreated with a terminal visible on half the screen and top running, load
goes high (2) but the cpu use is low, memory looks ok and io wait blips maybe
to 0.5 but not constant.

The system recovers after a period of time (say a minute, sometimes longer),
and the menu appears, but as soon as you click either a menu item (or one with
sub menu) or another main menu the process repeats.

My efforts to find a resolution included changing the graphics card and
upgrading from the stock 4.2 libreoffice supplied with xubuntu to 4.3 from the
ppa.

It was resolved using an addon/extension (name elludes me) which clears the
recent documents list. Performance then returned to normal.

The system has been working fine since it was installed in May 2014 and has
always stored its documents on samba over the vpn. It is used most days for
either calc or writer.

VPN performance was fine and tested.
