Bug 97523 – gnome-panel freezes for 5 minutes on gnome logout.

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Ivan Yosifov 2005-06-30 11:36:02 UTC]

When I click Desktop->LogOut in Gnome, the logout does not happen, the upper
panel freezes. The upper panel does not redraw, launchers on it don't respond
when clicked. Any applets on the upper panel work fine. The rest of the system,
including the lower panel and any open applications work fine. After several
minutes the upper panel unlocks and the logout takes place, or the logout
confirmation dialog comes up if configured to.

While the upper applet is hung netstat -t gives:

obelix@home ~ $ netstat -t
Active Internet connections (w/o servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State
tcp        0      1 localhost:60854         localhost:16001         SYN_SENT
obelix@home ~ $ lsof -i
COMMAND     PID   USER   FD   TYPE DEVICE SIZE NODE NAME
gnome-pan 14107 obelix   27u  IPv4  28613       TCP
localhost:60854->localhost:16001 (SYN_SENT)

This looks to me like a pending TCP connection attempt, by gnome-panel.

Suppose I have configured Gnome to show a logout confirmation dialog.
I click Desktop->LogOut, 5 minutes go by, the dialog comes up, I cancel the
logout. The next time I click Desktop->LogOut the dialog comes up right away as
it should. The panel hangs only the first time.

I am able to reproduce this with both my main account and a plain new account
created with useradd and copying /etc/skel as home directory.

obelix@home ~ $ grep 16001 /usr/include/esd.h
#define ESD_DEFAULT_PORT (16001)
obelix@home ~ $

Seems gnome-panel is trying to connect to esd.
In Desktop->Preferences->SoundPrefs. I have unchecked "Enable sound server
startup". If I check it, the 5 minute freeze is happening on log-in, so I guess
the freeze happens because of esd startup.

If I do 
/etc/init.d/esound start
before trying to logout from gnome, the freeze does not happen.
However on the next login I get a box saying:

I've detected a panel already running,
and will now exit.

[Comment 3 Ivan Yosifov 2005-07-04 12:57:04 UTC]

The freeze appears to have been caused by a fwbuilder bug. 
I don't get the freeze with a firehol firewall or no firwall.

However, the

Ok, since the freeze is no more and this was not even a Gnome bug,
I will close the bug and open an other one for the
