RHBA-2011:0360 - corosync bug fix update


Synopsis

corosync bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated corosync packages that fix a bug are now available for Red Hat Enterprise Linux 6.

Description

The corosync packages provide the Corosync Cluster Engine and C Application Programming Interfaces (APIs) for Red Hat Enterprise Linux cluster software.

This update fixes the following bug:

  • Compared to a unicast token, certain network switches add an extra delay to the transmission of a multicast packet. Consequent to this, multicast messages may have been retransmitted, even though the message was not lost and the retransmission was therefore not necessary. This update introduces the "miss_count_const" constant that allows a user to specify the maximum number of times a message is checked for retransmission before the retransmission is performed. (BZ#683592)

All users of corosync are advised to upgrade to these updated packages, which resolve this issue.

Solution

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.
