Occasionally, the RPM database on a CloudLinux machine can become corrupted. It can happen when an RPM transaction is interrupted at a critical time. Symptoms of this problem include one of the following programs not responding or freezing:
- The CLN alert notification tool (applet in the Gnome or KDE panel)
This problem can also cause a system to stop checking in with CLN. To fix this problem, run the following commands as root:
1. Kill all RPM and yum processes (rhn_check, yum, rpm, rhn-applet):
ps -axwww | grep rpm
In the list of processes, the first number on each line is the PID. For all PIDs listed except for the one associated with grep:
kill -9 <PID>
Repeat the above steps for each of the programs listed.
2. Remove any RPM lock files (/var/lib/rpm/__db*):
rm -rf /var/lib/rpm/__db*
3. Rebuild the RPM database:
