Starting an X program, fails with the message (on my 3rd X server): Xlib: connection to ":2.0" refused by server Xlib: Maximum number of clients reached xterm Xt error: Can't open display: :2 Reproducible: Sometimes Steps to Reproduce: 1.Start a few X programs such as Firefox, Thunderbird. 2.

This has been happening with different versions of xorg-x11 in XFCE4, although I've reproduced it in KDE and Gnome.

I had the same problem 2 or 3 times now. xrestop showed ~254 clients (255 is the maximum I think). I had the feeling it has something to do with Mozilla or Firefox. So I restartet X and tried to reproduce it with Mozilla/Firefox but everything's okay so far...
I can too reproduce this error, running gnome with firefox and several other programs.

What can I do to diagnose this problem?
You may wish to file this upstream at bugs.freedesktop.org.
1.Start a few X programs such as Firefox, Thunderbird. 2. (Unknown step) 3.Start another X program, such as xmms. I'm not running Firefox or Thunderbird and unknown step seems to be "leave computer on for a few days".

I think I said, file it upstream, not, comment more on this. Nothing's going to happen on this bug unless you do it yourself, as long as it's a Gentoo bug and not an upstream one.
At this point, we don't know if it's a gentoo specific bug or not, and as other here had the same problem I was hoping to get som info to compare with. If I then manage to track down the bug I could file it upstream.
Ok, done. https://bugs.freedesktop.org/show_bug.cgi?id=2920
Thanks :)
Is it possible that this is a Mozilla/Firefox issue? I have the very same problem and it happens always while browsing) (see https://bugzilla.mozilla.org/show_bug.cgi?id=179369 for a older reference)
Apparently the upstream author is trying to kick this back down http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=325689 Maybe it's fixed in 2.6.5?
Updating URL to reflect that we're now tracking there. Activity seems to indicate it's an xloadimage problem; re-assigning.
desktop-misc, I'll leave re-naming and status of bug up to you, if you so desire.
Created attachment 71741 [details, diff] xloadimage.4.1.resource.patch With this patch applied I couldn't see the leak, but it requires more testing.
Daniel - could You test the patch?
Waiting for test.
Created attachment 76190 [details, diff] xloadimage-4.1.resource.patch Corrected patch.
