284277 - [win] firefox keeps restarting with profile on unc path

Status: UNCONFIRMED

(Toolkit :: Startup and Profile System, defect)

Description

[Jörn Nettingsmeier]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041109 Firefox/1.0
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041109 Firefox/1.0

severe thunderbird and firefox bug:

clients are w2k w/ latest sp and hotfixes, users work with restricted rights.
thunderbird/firefox are release 1.0 (german localization)
domain logon with roaming profiles, home directories are on the server, and
thus we have unc paths in the prefs.js file.
server is samba 3.0.11 on linux

for some users, thunderbird or firefox hangs after startup (hourglass/no window
opens). 
"smbstatus" on the samba server tells me the client holds locks on parent.lock
and xpti.dat, which
keeps changing size and is occasionally renamed to xpti.dat.tmp.

taskmgr on the client shows a very
busy thunderbird/firefox.exe process with lots of i/o and *changing process id* !!!
wtf ????
the rapidly changing pid makes it almost impossible to kill in the task manager.
the programs generate a network load of around to 5-6 mbit/s while hanging.


the problem appears with some users, but if it happens, it happens every time.
with one user, changing the default browser to firefox (as admin) triggered the
problem.


(i'm not sure which component the problem belongs to. please, moz gurus, direct
it to the appropriate one...sorry)

Reproducible: Sometimes

Steps to Reproduce:
1. start firefox or thunderbird
2.
3.

Actual Results:  
program should start

Expected Results:  
program hangs before a window opens

i see you changed it to product "firefox". just to reiterate, this happens on
both thunderbird and firefox.
i'll try and delete the xpti.dat files of affected users and see if it makes a
difference. can't reproduce the problem with my account, so that will have to
wait until tomorrow.

ok, i deleted xpti, compreq and XUL in the profile directory, but it did not
make a difference. same race.

it is definitely not. i have checked, there are no extensions, neither global
nor in the user profile. the problem persists even when i delete that user's
firefox profile and start over.

This probably has something to do with the many "profile on network drive not
good" bugs. Are the home directories on mapped drive letters, or directly on
\\SERVER\Paths?

they are on unc paths. homes are on \\%LOGONSERVER%\%USERNAME%, and the
"application data" (or rather "anwendungsdaten", since we have a german w2k) dir
has been removed from the profile (i.e. it's not copied back and forth on
login/out) and was relocated to \\%LOGONSERVER%\%USERNAME\.winprofile.

we also have Y: mapped to \\%LOGONSERVER%\%USERNAME% because of a bug in mozilla
application suite up to 1.7.3 that prevented it from opening mail folders when
there are unc paths in the prefs.js, but it is not used in any new thunderbird
and firefox profiles.

I'm not going to get a chance to look at this any time soon. Diagnosis of *what*
is failing would be very helpful.
