I'm having this same issue with lab computers I'm administering. In
both cases (so far), the commonalities are:
- the systems run 9.04
- the home directory for the user is mounted via CIFS (samba) from a fileserver
Notably, there are around 5 or so 9.04 systems in the lab -- which do
not mount the home directory via CIFS -- that do not exhibit this
problem. Only the CIFS-mounting systems.
My "breakthrough" in troubleshooting this was to run an strace(1) on the
fileserver against the user's smbd process. Upon login, the following
looped interminably:
"
read(23, "\0\0\0\252"..., 4) = 4
read(23,
"\377SMB2\0\0\0\0\0\1\300\0\0\0\0\0\0\0\0\0\0\0\0\1\0\1ld\0\271A\17"..., 170) =
170
stat(".pulse/7692ed27d65b84c17c3cdda449bebb23:runtime", 0x7fffffc94f00) = -1
ENOENT (No such file or directory)
lstat(".pulse/7692ed27d65b84c17c3cdda449bebb23:runtime", {st_mode=S_IFLNK|0777,
st_size=23, ...}) = 0
fcntl(11, F_SETLKW, {type=F_RDLCK, whence=SEEK_SET, start=17872, len=1}) = 0
fcntl(11, F_SETLKW, {type=F_UNLCK, whence=SEEK_SET, start=17872, len=1}) = 0
readlink(".pulse/7692ed27d65b84c17c3cdda449bebb23:runtime",
"/tmp/pulse-6yCwltbxKn5h"..., 4096) = 23
write(23,
"\0\0\0l\377SMB2\0\0\0\0\200\1\300\0\0\0\0\0\0\0\0\0\0\0\0\1\0\1ld"..., 112) =
112
select(24, [19 23], [], NULL, {57, 81589}) = 1 (in [23], left {57, 72000})
"
Note the critical line showing that file
.pulse/7692...blahblah...bebb23:runtime cannot be found. Looking at
this file on disk, it turns out to be a symlink to a file such as /tmp
/pulse-6yCwltbxKn5h, the latter which doesn't exist, thus creating a
broken symlink situation. So it seems that Pulse gets hung up on this
and stalls the entire login process.
The workaround for me was to remove the symlink, which would then force
a new /tmp/pulse-XXX file to be created with a proper symlink in the
user's home directory, and the login would proceed successfully!
I've confirmed that this workaround works on both affected systems.
I'm not sure what the underlying _cause_ is, however, and am worried
whether this will pop up in the future or not, thus any help is
appreciated.
