[Bug 641632] [NEW] [maverick] upgrade process cannot stop smbd, prerm script hangs and blocks upgrade process

[Zorael]

Public bug reported:

Binary package hint: samba

Kubuntu maverick, packages updated daily.

When upgrading to samba version 2:3.5.4~dfsg-1ubuntu7, the prerm script
for said package hangs, and the upgrade process is blocked from
proceeding to other packages.

Grepping the process table for 'samba' and 'smb', there is a persistent
entry for 'stop smbd' as well as an entry for the prerm script. The smbd
daemon itself was not listed as running.

    root     24211  0.0  0.0   4148   576 pts/6    S+   15:25   0:00 /bin/sh /var/lib/dpkg/info/samba.prerm upgrade 2:3.5.4~dfsg-1ubuntu7
    root     24214  0.0  0.0  21408   876 pts/6    S+   15:25   0:00 stop smbd

Attempting to run 'sudo stop smbd' from another terminal only yielded the following;
    stop: Job has already been stopped: smbd

Killing the 'stop smbd' process with 'sudo kill <pid>' allowed the
upgrade to proceed. I'm attaching a log of the aptitude upgrade process,
with a small comment where it froze.

Apologies for the paste spam.
