RHBA-2011:1361 - corosync bug fix update

Synopsis

corosync bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated corosync packages that fix several bugs 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 bugs:

  • Previously, under heavy traffic, receive buffers sometimes overflowed, causing loss of packets. Consequently, retransmit list error messages appeared in the log files. This bug has been fixed, incoming messages are now processed more frequently, and the retransmit list error messages no longer appear in the described scenario. (BZ#726608)

  • Previously, when a combination of a lossy network and a large number of configuration changes was used with corosync, corosync sometimes terminated unexpectedly. This bug has been fixed, and corosync no longer crashes in the described scenario. (BZ#727962)

  • Prior to this update, when corosync ran the "cman_tool join" and "cman_tool leave" commands in a loop, corosync sometimes terminated unexpectedly. This bug has been fixed, and corosync no longer crashes in the described scenario. (BZ#734997)

All users of corosync are advised to upgrade to these updated packages, which fix these bugs.
