1.20.1. RHBA-2010:0517: bug fix update

Updated db4 packages that fix a database verification bug are now available.
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.
This update fixes the following bug:
* IDs (ID lists) are stored as "duplicate" nested btrees. When such a list grew big enough enough to require internal pages, the dbverify utility reported spurious out-of-order errors as follows (note: the page and entry numbers are context dependent):
db_verify: Page 7: out-of-order key at entry 6
These errors presented because dbverify did not distinguish between the main database tree and off-page-duplicate trees. With this update, dbverify now distinguishes between such trees and the spurious errors no longer occur. ( BZ#589880)
All users should upgrade to these updated packages, which resolve this issue.
