Summary: All of LibreOffice 4.x hangs if LibreOffice Base 4.x
is running when switching between video console and
RDP session
Severity: normal
Classification: Unclassified
OS: Windows (All)
Reporter: [email protected]
Hardware: x86 (IA32)
Status: UNCONFIRMED
Version: 4.1.3.2 release
Component: Database
Product: LibreOffice
I use LibreOffice 4.x on Windows 7 Professional for x86-32 on incubus, my
primary desktop computer at my residence. When I am at my residence, I use the
video console of incubus. At my employer’s shop, I use a different desktop
computer, succubus, which runs Windows 8 Enterprise RTM for x86-32. incubus
and succubus are both on the same Hamachi Virtual LAN. When I am at my
employer’s shop, I use succubus as an RDP client to control incubus over the
Hamachi Virtual LAN. If only LibreOffice Writer 4.x is running when I switch
between using the video console and RDP session, LibreOffice Writer 4.x is
still functional after the switch. However, if LibreOffice Base 4.x is running
when I switch between using the video console and RDP session, then all of
LibreOffice 4.x hangs after the switch: the windows of the LibreOffice 4.x
applications stop responding, which forces me to terminate LibreOffice 4.x . I
usually have only LibreOffice Writer 4.x running in addition to LibreOffice
Base 4.x when switching between the video console and RDP session: I know that
LibreOffice Writer 4.x hangs in addition to LibreOffice Base 4.x if LibreOffice
Base 4.x is running when switching but I do not know if other LibreOffice 4.x
applications will hang too if LibreOffice Base 4.x is running when switching.
I expect that the other LibreOffice 4.x applications will hang too. Of those
applications, I expect that Calc is most likely for me to leave running in
addition to Writer and Base.
I need all of LibreOffice 4.x to remain functional when switching between the
video console and RDP session even if LibreOffice Base 4.x is running when
switching. IIRC, I did not have this problem with LibreOffice 3.x but I cannot
currently test with LibreOffice 3.x because I no longer have LibreOffice 3.x
installed on incubus.
I have some other configuration details that may not be relevant but I will
mention them in case they are relevant:
1. Both my residence and my employer’s shop use a Wired LAN (Ethernet over
twisted pair cable) using only Ethernet switches, no Ethernet hubs. Both sites
have a Wireless LAN too but both incubus and succubus use only the Wired LAN.
At both sites, the physical Wired LAN and the physical Wireless LAN are a
single logical Virtual LAN using a MAC bridge. At both sites, the wired
gateway runs DD-WRT and uses Telus ADSL service for its uplink (to the WAN).
2. Both incubus and succubus are dual-head with a 21-inch Trinitron CRT
computer display at 1600×1200 at 85 Hz on the left and a 27-inch Samsung
SyncMaster 275T Plus (for incubus) or Samsung SyncMaster 275T (plain 275T, not
275T Plus; for succubus) at 1920×1200 on the right. For both incubus and
succubus, the CRT is the primary display and the LCD is the secondary display.
3. succubus uses a stock kernel with crippled support for the Physical Address
Extension (PAE) capability of the x86 CPU because succubus has only 4 GiB of
main memory, which seems to suffice for my usage because succubus usually runs
much less at once than incubus. However, incubus uses an unofficially patched
kernel to undo Microsoft’s intentional crippling of the PAE support in the
client editions of Windows NT for x86-32 because incubus has 8 GiB of main
memory because incubus always runs a lot of software at once, which usually
uses more than 4 GiB of physical RAM. I mention this unofficially patched
kernel because the Windows 7 kernel is from Windows 7 RTM but most of the rest
of the Windows 7 installation is from Windows 7 SP1. This unusual software
configuration usually seems to work well but Microsoft says that they
intentionally crippled the PAE support to limit access to only the first 4 GiB
of RAM because some third-party device drivers have not been tested with memory
addresses above 4 GiB: Microsoft says that such faulty device drivers can
corrupt memory if the kernel uses the PAE to access more than 4 GiB of RAM. I
guess I should try to test with the stock crippled Windows 7 kernel but
rebooting incubus to switch kernels is very inconvenient for me and can be done
only when I am physically at my residence. I cannot use Windows NT for x86-64
because I need specific backward compatibility that only Windows NT for x86-32
provides.
Please tell me if you need any more information from me.
