MASTER Firefox makes X run out windows

[André Cruz]

Binary package hint: firefox

After letting firefox run for some days I started getting this error every time I tried to start an X application:

Xlib: connection to ":0.0" refused by server
Xlib: Maximum number of clients reached
cannot open display:

I then closed some applications so that I could use xwininfo and xlsclients.

andre@huge:~/downloads$

Notice the number of windows with no name...

I then closed Firefox and the number of windows dropped dramatically and those no name windows disappeared:

andre@huge:~/downloads$ xwininfo -root -children | wc -l
101
andre@huge:~/downloads$

Just to test I started firefox again, it opened the same tabs and the number of windows increased by 20, not by 250 as it was before.

[meba (jakub-rtfm)]

I can confirm this. Same symptoms. Also reported here: http://ubuntuforums.org/showthread.php?t=133719

[Rocco Stanzione (trappist)]

I can confirm as well. I haven't even been running X for but a few hours, so it seems likely that certain websites (looks to be an xloadimage issue) or certain browsing behavior might be causing it? It's a little tough to track it down to firefox. I said `sudo lsof -p 24329 | grep /tmp/.X11-unix/X0 | wc -l` where 24329 is the pid of X, and it reported 244 before closing firefox and 16 after.

[Rthaduthd Anthnhkrc (nthnuekeu-deactivatedaccount)]

can confirm this .. seems like closing down firefox helps

..kind of annoying..

[Ext-andre-pedralho (ext-andre-pedralho)]

After long periods of time working Firefox opens many non-visible windows and the Xlib reaches its maximum number of clients allowed. Then, it is impossible to run any other application. If I try to do it I have the following answer from Xlib:

Xlib: connection to ":0.0" refused by server
Xlib: Maximum number of clients reached
xlsclients: unable to open display ":0.0"

You can verify my supposing using the following commands when this limit reaches:
# xlsclients | wc -l
26
# xwininfo -root -children | wc -l
1028

André, as you reported it here, may I assume that you were able reproduce this with vanilla firefox install from ftp.mozilla.org (vs. ubuntu's only)?

I can try this. I stopped to get this bug since I started to use the Tab Mix (http://tmp.garyr.net/) add-on.

[Alexander Sack (asac)]

if you see this "X run out of windows" bug in firefox, please post what extensions you have installed.

[Alexander Sack (asac)]

not reproducible ... need a testcase

[Rthaduthd Anthnhkrc (nthnuekeu-deactivatedaccount)]

it hasn't happened for a long time here .. i'm not sure what caused it

(2-3 days ago - i upgraded from edgy to feisty also .. haven't seen it yet here either)

[Ext-andre-pedralho (ext-andre-pedralho)]

I tested it for some days using the bon-echo version. I got the source code and compiled myself and I couldn't reproduce the bug. I would be a ubuntu packaging issue.

[Alexander Sack (asac)]

André, so can you still reproduce with latest ubuntu version as well?

[John Vivirito (gnomefreak)]

I am unable to reproduce this in edgy or feisty. Can you please post a step by step set of instructions on what you do to reproduce this. including sites that this happens on. Thank you.

> André, so can you still reproduce with latest ubuntu version as well?

Yes, I can. I tried the 2.0.0.2+1-0ubuntu1 and I still getting the same environment:

It was working fine with the following results:
xlsclients | wc -l
30
xwininfo -root -children | wc -l
800

After the first frame pops-up I got the following results (I got this when I tried to write a email using the yahoo mail beta, I think because it tries to create 4 internal frames using AJAX and those frames got the NULL value as parent):
xlsclients | wc -l
30
xwininfo -root -children | wc -l
804

Maybe the Firefox installed and the GTK+ installed are incompatible. I mean, perhaps Firefox was compiled using another GTK+ version than I have here (2.10.9-0ubuntu2).

It may be creating a lot of memory leaks. Do you have any tools for getting where it is occurring, if it is occurring?

[Alexander Sack (asac)]

can you try to extract some testcase to reproduce? what page to visit and what to do in order to get this problem? maybe also: what extension is needed to get this etc.

Well, I just could reproduce this bug after a long navigation period (I mean more than 4 days without close the browser). I just used FF without any extensions.

Do you have any suggestions about testcases or tools?

[TheOverclocked (jordan-theoverclocked)]

Well I got this error tonight and logged everything very well (I hope) so that we can figure out what is causing this.

I decided to post all my logs and crap up in my blog so that it doesn't clutter up this bug report.

You can find all of the data I collected here -> http://blogs.theoverclocked.com/jordan/index.php/2007/03/23/firefox-makes-x-run-out-windows/

I hope this helps!!!!!

I got the same error even using this extension in Firefox 2.0.0.3.

Marking as in progress as upstream has confirmed it.

I started getting this bug on Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.8.1.4) Gecko/20070603 Fedora/2.0.0.4-2.fc7 Firefox/2.0.0.4 after installing gnash-plugin (the plugin to use the gnash flash-player with Mozilla browsers) version 0.7.2-2. It didn't take a long period of browsing before the maximum number of windows was reached, i.e. it occurred fairly soon after starting or restarting Firefox.

After uninstalling the gnash plugin, the problem seems to have disappeared entirely.

Is there any further info I can provide that would be useful?

[cburroughs (chris-burroughs)]

Daniel,
Do you have the the Macromeadia flash plugin installed? Have you still not seen this behavior sicne 2007-06-20?

[Daniel-holt (daniel-holt)]

I did not now or ever install Adobe's flash player; and I have still not seen this behavior since last commenting.

ffox 3 appears to not have this issue. imo its unlikely that ffox 2 will still get a proper solution. setting status to reflect that.

This bug is back. It's been happening off and on ever since I upgraded to Fedora 9 a while back. I've only now traced it down to Firefox as the cause.

[Zack Cornelius (zcornelius)]

I can confirm this bug has reappeared in Ubuntu Hardy and Intrepid

Currently running "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.1) Gecko/2008071816 Ubuntu/8.10 (intrepid) Firefox/3.0.1"

I get this problem after 2 or 3 days of browsing.

[Jruderman (jruderman)]

kmike thinks this might be a duplicate of bug 263160.

[Karlt (karlt)]

Comment 9 and 10 is definitely bug 263160.

I don't know that would result in
"Xlib: connection to ":0.0" refused by server
 Xlib: Maximum number of clients reached"
though.

[I2nm5ho7a (i2nm5ho7a)]

Is this bug still relevant since flash and gnash are no longer supported. Or can this bug be closed by now?

[Db48x (db48x)]

Wow, I haven’t seen this problem in a while. Just close the bug and hope nobody ever has to report a similar one.
