During a normal day of browsing, Moz freezes several times with the CPU at about
100%.  It seems that certain pages trigger the freezing behavior.  It also seems
that the user's font preferences influence whether a particular page will cause
Moz to freeze.  Certain URL/font combinations cause the freezing Every Time. 
The URL I have provided causes the problem when the Bitsteam Vera family of
fonts are used in the default serif, sans serif, and monospaced positions on my
Red Hat Linux 8.0 configuration with an upgraded FreeType (2.1.4).

I have been able to reproduce the freezing using other font preferences.  I have
been able to reproduce the problem using the official
mozilla-1.3-0_rh8_xft.i386.rpm download as well as the contributed
mozilla-1.4a-0_rh8_gtk2.i386.rpm.  The backtraces look the same, regardless of
the font preference, and so I'll include one backtrace for Moz 1.3 and one for
Moz 1.4a.

Possible clue:  I tend to use TrueType fonts, not Adobe Type1.


Reproducible: Always

Steps to Reproduce:
1.  In Edit -> Prefs -> Appearance -> Fonts, select TrueType fonts for your
defaults.  (This may not be necessary, but I'm including it for completeness.)
2.  Surf around.  Try the URL I provided, but you may have to surf for a while
to find a page that triggers the behavior.
3.  Mozilla will freeze in a CPU-consuming loop.

Actual Results:  
Mozilla froze.  CPU usage was pegged.

Expected Results:  
Mozilla shoud have rendered the page.

You may need to have this font installed to trigger the freezing.  My copy of

Another backtrace.  Like the others, this was captured when Moz froze.	I just
attached to the process w/ gdb and used the bt command.
Dup of 183729?
Blocks: xft_triage
I can confirm this on 
Debian. This has been happening as long as I can remember when Mozilla has been
compiled with GTK2 and Xft, and it seems to only be getting worse with time -
it's now down to about 1-3 hours of normal browsing before Mozilla becomes
completely unusable, using 100% CPU before it has to be killed. Nobody has
pointed out any other possible duplicates, so marking this as NEW.
Status: UNCONFIRMED → NEW
Ever confirmed: true
I see the same thing without using gtk2. I've seen this since I started to use
Xft which feels like a year ago. I've not reported it since I've never been able
to make something reproducable (and I still can't). After like a minute or so
the 100% CPU usage goes down but as soon as he wants to draw text again it's up
to 100%. Opening the menu to choose Quit can take 30-60s when this bug is triggered.

Sorry to make such a useless comment, but maybe it can help someone.
I got into the same problem again a while ago, where it took 1 minute to show a
page that normaly takes 1s. I attached strace to it and saw that most of the
syscalls was writes to FD 3, which is a unix socket that I think is the
connection to X (/tmp/.X11-unix/X0). Apart from all the writes to FD 3 there was
also a big amount of calls to gettimeofday. Unfortunatly the strace log was lost
but I'm sure I can attach strace to mozilla the next time to capture it if
someone is interested.

Is there some tool I can use to connect to a running X-connection and see what
commands that is sent to X. Like strace but for X. If I can just figure out what
mozilla is doing when it sits there for a minute with 100% CPU it would be so
much easier to write a bug report.
Sure, check out something like xscope:

This is a very bizarre bug. Both Galeon and Mozilla on one computer running
Debian sid exhibit this behavior after only a couple of hours of normal
browsing. Whereas another computer, running an almost identical distribution of
Debian sid, do not have this bug on either Mozilla or Galeon.
Interesting news:  I had a similar freeze-up while surfing in Opera (which I was
using only to avoid these free-ups in the first place!).  Taking a gdb backtrace
reveals the same kind of Xft-related problems.

In other words, this may not be a Moz bug but some kind of Xft/freetype problem.
 Nevertheless, we might want to identify what Moz is doing to trigger the nasty
behavior.  If there's an Xft/freetype landmine somewhere, I prefer that Moz not
jump on it so often.  

One clue is that the Gnome Bitstream Vera faces seem to be a catalyst for the
problem on my RH 8.0 desktop.  More data needed.

ALL CONTRIBUTERS TO THIS BUG:  If you have had this kind of freeze-up on your
sytem, what fonts were you using as your Moz defaults?  What versions of X, Xft,
fontconfig, and freetype were you using?
I use Bitstream Vera as the default fonts on both computers, but as I said
earlier, the problem only shows up on one of the computers.
I get this as well, happening every 10 minutes or so.

Happens in all of:  Firebird/0.6 Gecko/20030519, Galeon 1.3.4 Gecko/20030430,
and CVS Mozilla.

Bitstream Vera fonts as default.

Debian unstable:

libxft2: 2.1.1-2
xserver-xfree86: 4.2.1-6
libfreetype6:  2.1.4-2

Of note, CVS mozilla (mozilla-snapshot from Debian) is not, I belive, built
using GTK2, so I wouldn't blame that.

Blame definitely seems to be towards xft/freetype.

I'll post here later when it happens again, with an strace -p snippet, if it
looks interesting.
All Debian Mozilla builds use gtk2.

Package: mozilla-browser-snapshot
Version: 0.0.20030520.12.trunk-1
Depends: libgtk2.0-0 (>= 2.2.1)
This looks like a dup of bug 173204. Make sure you have a version of X _higher_
than 4.2.1.
Blocks: xft_tracking
I'm running X 4.3.0, ironically, on the system that freezes with Mozilla.
Keith, any idea? I have never come across this bug, but that's probably because
I don't have Bitstream Vera installed. I'll try to reproduce it with Bitstream
Vera fonts installed and a debug build of Xft. 
I'm not seeing this bug anymore with the latest version of Firefox & latest
Debian revision of X 4.3.0.
Sometimes Firefox becomes extremely slow, to the point that one might think it
froze. The stack trace shows it hanging out in XFT code on RH 9. Attaching
trace to this bug because the description and trace are similar. If somebody
that knows about XFT and/or Linux stuff could triage it that would be great.
The stack trace I just posted is from Firefox 0.9.3. Please consider nominating 
for aviary 1.0 blocker. I'm not sure if traces from this would show up in 
trackback since the browser hangs and doesn't really crash.

I saw only one comment about the xft version in use and that one mentioned 2.1.1
which had a bug in cache management which would (eventually) reduce the active
memory to a single glyph, which would cause thrashing in Xft.

2.1.2 or newer should have this bug fixed.  There are only minor fixes after
that point which shouldn't have any effect on this bug, but testing with 2.1.6
would be nice to rule that out.

I have not seen behaviour like this since 2.1.1.
It seems this was WFM for everyone by the last comment.
If this bug still occurs in a recent trunk build, with the minimum
platform requirements listed here:
http://wiki.mozilla.org/Linux/Runtime_Requirements
then please open a new bug on GFX:Thebes.  Thanks.
