758978 The previous version of Red Hat Directory Server
used the NSPR implementation of reader/writer
locks (rwlocks). However, this implementation
does not allow the use of re-entrant locks and
consequent to this, an attempt to perform multiple
concurrent searches with large search filters and
many DN syntax attributes may have led to the
server deadlock. With this update, the server has
been adapted to use POSIX rwlocks on Linux
platforms. As a result, deadlocks no longer occur
in this scenario.
767273 Due to excessive DN normalization, multiple
concurrent searches with large search filters with
many DN syntax attributes could cause the
server to use an inordinate amount of CPU. This
update introduces a new configuration attribute,
nsslapd-normalize-nested-dn, which allows users
to turn the DN normalization off, resolving this
issue.

748575 Repeated modrdn operations caused
performance problems in replicated environments
and caused the ns-slapd process to repeatedly
hit 100% CPU usage.
750622 SASL bind operations could cause the server to
leak memory.

709468 When performing an LDAP search operation
using the Simple Paged Results Control, if the
connection was left idle for longer than specified
in the search operation's timelimit, the directory
server timed out and closed the connection, and
the console returned time out errors. With this
update, when the client reads all of the results to
completion, the server resets the search
operation's time out and the idle connection is not
closed until the server's own idle timeout
threshold is reached.
697694 In some specific circumstances under a heavy
replication update load with multiple masters, the
master's error log would sometimes record "Bad
parameter to an LDAP routine," followed by
"stop_fatal_error" and "requires administrator
action" messages. With this update, these errors
no longer occur.

606920 If the client specified the "sizelimit" or "timelimit"
option with the search request, the specified limit
was not honored by the Directory Manager. This
problem has been fixed so that the limit is now
