   Hello Users of LibreOffice,

Once in a while I visit the Release Plan wiki page,

  From that wiki page, I recently tried to visit the "5.0.2" -> "RC1"
page (more than once), but my OS hangs when I click on the relevant

Of course, it could be just a coincidence. I am reluctant to try to
reach these pages again, especially considering that every new wiki
page in the series is based on the prior one.

I am using Windows Vista Home Basic 32-bit, with Internet Explorer 9
and Mozilla Firefox 40.0.3, all updated.

The strange behavior happened with both web browsers.

I don't know whether some security tool being in use (e.g. Avast)
might be relevant.

I wanted to share this unusual experience, in case someone else
happens to see it too (or something similar, or at least uncommon),
and/or maybe it might be worth someone checking the source of these
wiki pages (and their related nested templates).

I am aware that this behavior (hanging OS) would be considered
"unlikely to be triggered by some wiki page". The fact that it
happened to me more than once while following the same links (but
nowhere else) pushed me to at least comment on it.

Interesting... I don't see a problem with that page at the moment.
However, since mid July I have been experiencing occasional OS hangs
which seem to be triggered by visiting certain web pages or sometimes
scrolling down the page slightly even after it's been loaded for a
while. Revisiting the same page doesn't necessarily trigger another
hang, but some pages seem to be more prone to it than others.

I use Windows Vista Business 32-bit, Mozilla SeaMonkey 2.33.1 (based
on Firefox 36), Avast antivirus.

One site ( seemed to be particularly
troublesome. At one point I couldn't even add a few items to the
shopping cart and check out before the OS hung. Hangs seemed to be
less frequent using Chrome instead, but I did still get a few. I
didn't try IE.

I haven't had so much trouble since mid August, but then again I
haven't been visiting the sites which seemed to be triggering the
problem so much lately either. Still get a couple of unexplained hangs
a week though.

I can't be certain that visiting the web sites is/was the trigger, or
whether that's just coincidental. As you say, it does seem unlikely!
If anything, I'd suspect some interaction with a Windows update or
perhaps Flash or Avast, since I'd just got back from holiday and
installed a load of updates just before the problems started. Another
possibility for me is overheating or failing hardware (this is a 9
year old laptop so getting on a bit!) but I haven't got around to
investigating further.


So, when the problem happens for you, what do you do to recover?  How do
you get the system working again?  Have you checked the Windows Event
Viewer for log messages?  There might be a log message around the time
the system hangs.


"The Other"  Tom

For me the whole OS completely hangs and I have to kill the power (press
and hold power button for a few seconds). Ctrl+Alt+Del does nothing, mouse
pointer doesn't move, and num lock / caps lock don't respond (they often at
least toggle the keyboard lights even if nothing else responds; in this
case even that stops responding).

I haven't got around to investigating thoroughly, but things I have tried
- Just leaving it for over half an hour to see if it would start
responding again; it didn't.
- Checking event logs; there's nothing obviously relevant, except the
expected complaints during the next startup related to not having been shut
down properly.
- Keeping Task Manager / Sysinternals Process Explorer open before it
hangs, but there's no obvious peak in processor or memory usage, or any
particular process's activity - but they might just not get a chance to
update the display when it does hang.
- Some of the memory and CPU load tests from, but
they didn't reveal anything and didn't hang.

Can't actually remember whether I checked the disk for errors, I think I
did but may be worth doing again.

At some point when I have enough time I'll get the lid off and check fans,
heatsinks, etc. I'm half expecting to find dust or spiders clogging things

The common thing with Ady is that you both have the Avast Antivirus. An
antivirus runs as a "system service" on Windows,
and if something goes terribly wrong in the system service, then the whole
operating system may misbehave.
Since you do not have yet a set of steps to reproduce the problem, it is
extremely difficult to figure out the issue.
