RPM/yum Database Corruption

Jumped onto my server and noticed a few out of date packages. A quick % sudo yum update reported the following:

error: rpmdb: BDB0113 Thread/process 12323/139745043400512 failed: BDB1507 Thread died in Berkeley DB library
error: db5 error(-30973) from dbenv->failchk: BDB0087 DB_RUNRECOVERY: Fatal error, run database recovery
error: cannot open Packages index using db5 - (-30973)
error: cannot open Packages database in /var/lib/rpm
CRITICAL:yum.main:

Fortunately, the fix was easy:
% sudo rpm --rebuilddb

Once complete, yum update worked like new.
