Comment 29 for bug 58171

When this problem is happening:
- OpenOffice does not start
- vim is starts slowly
- It takes 7 seconds to open an xterm window

The socket in /tmp/.ICE-unix/ has a different number than the one programs are looking for.

I time over 7 s when I start xterm and close the window as soon as it appears:
$ time xterm
Warning: Tried to connect to session manager, Could not open network socket
real 0m7.374s
...

Vim starts slowly, strace mentions ICE-unix
$ strace vim newfile.txt
...
nanosleep({1, 0}, {1, 0}) = 0
socket(PF_FILE, SOCK_STREAM, 0) = 3
uname({sys="Linux", node="foobar", ...}) = 0
connect(3, {sa_family=AF_FILE, path="/tmp/.ICE-unix/6026"}, 21) = -1 ENOENT (No
such file or directory)
close(3)

Indeed, this /tmp/.ICE-unix/6026 does not exist. Instead, a similarly named socket with a different number is found:
$ ls -ld /tmp/.ICE-unix/ /tmp/.ICE-unix/*
drwxrwxrwt 2 root root 4096 2008-08-11 12:33 /tmp/.ICE-unix/
srwxrwxrwx 1 tero tero 0 2008-08-11 12:33 /tmp/.ICE-unix/6943

Don't know if this is related, but localhost and hostname are mapped to different IP's in the loopback block.
$ cat /etc/hosts
...
127.0.0.1 localhost
127.0.1.1 foobar
...

Running Ubuntu 8.04.1 hardy. IPv6 is not disabled. Currently, DNS resolution is quite slow, don't know if it is related. I have network-manager 0.6.6-0ubuntu5, xserver-xorg 1:7.3+10ubuntu10.2, xterm 229-1ubuntu1, vim 1:7.1-138+1ubuntu3.
