How do you mount your home directory on your client ?

[Bug 250655] [NEW] samba daemon deadlocks

2008-07-21 Thread Jaap Versteegh
Public bug reported:

Binary package hint: samba

I have firefox's (3.0) profile  stored on a samba share. Ocasionally (about 
twice a day) when entering data into a webcontrol, firefox freezes. The cause 
seems to be the samba daemon on the server that deadlocks. A new samba daemon 
is spawned after a few seconds, but the dead daemon remains in memory and also 
keeps locking the firefox profile directory. It can only be killed with kill -9.
Connecting to the dead daemon with gdb produces the following callstack:
#0  0x7faf9272023e in __lll_lock_wait_private () from /lib/libc.so.6

Ubuntu is a completely up-to-date 8.04 (on both desktop and server machines).
Samba installed on the server is:
Architecture: amd64
Version: 3.0.28a-1ubuntu4.4

Smb.conf is added as an attachment.

Files in /var/log/samba have no entries at the time of the deadlock
occurence.
