Bug 518125

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.0) Gecko/20090617 SUSE/3.5.0-2.2 Firefox/3.5

While installing a large number of packages (I was trying to install the gnome patterns from the internet) zypper hangs (after some packages have been installed) attempting to install a package. This happens randomly and zypper actually shows that the package has been retrieved successfully at 0 B/s (which is strange, considering it shows the correct speed for all earlier packages), but the install hangs at 0%. Only a Ctrl-C Ctrl-C sequence works and the following message is then shown

"Installation of gnome-panel-2.26.2-1.9 failed:
(with --nodeps --force) Error: Subprocess failed. Error: RPM failed: warning: waiting for transaction lock on /var/lib/rpm/__db.000"

Problem also occurs with YAST, in which case only killing y2base as root is the only way out. Once this error happens, it keeps re-occurring every time the software management is used subsequently. One has to restart for the problem to disappear.

Reproducible: Sometimes

Steps to Reproduce:
1.Select a large number of packages to install using zypper or YAST.
2.At some stage process hangs trying to install a package at 0%
3.Kill install procedure and try again. Error persists.
4.Restart, and attempt installation. Works until error occurs randomly again.
Actual Results:  
Installation fails with message:
"(with --nodeps --force) Error: Subprocess failed. Error: RPM failed: warning: waiting for transaction lock on /var/lib/rpm/__db.00"

Expected Results:  
Installation successful.
