Updated db4 packages that fix one bug are now available for Red Hat Enterprise Linux 6.
The Berkeley Database (Berkeley DB) is a programmatic toolkit that provides embedded database support for both traditional and client/server applications. The Berkeley DB includes B+tree, Extended Linear Hashing, Fixed and Variable-length record access methods, transactions, locking, logging, shared memory caching, and database recovery. The Berkeley DB supports C, C++, Java, and Perl APIs. It is used by many applications, including Python and Perl, so this should be installed on all systems.
Due to an incorrect order of the mutex initialization calls, the rpm utility became unresponsive under certain circumstances, until it was terminated. With this update, the order of mutex initialization calls has been revised. As a result, the rpm utility no longer becomes unresponsive.
Users of db4 are advised to upgrade to these updated packages, which fix this bug.
