Comment 39 for bug 347983

bug #268261: this fix is critical, as we had customer installations being bitten by this bug before. smart would just hang there, doing nothing but blocking itself. As a result, landscape would not be able to manage the packages of this machine.

This still happens:
andreas@nsn2:~/canonical/scripts/queries$ ./search-stuck-smart.py 30
Computers where smart is stuck and that contacted us in the last 30 days:
xxxx
yyyy

The script above queries the landscape database. I sanitized its output.
