4.133. piranha

Updated piranha packages that fix two bugs are now available for Red Hat Enterprise Linux 5.
Piranha provides high-availability and load balancing services for Red Hat Enterprise Linux. The piranha packages contains various tools to administer and configure the Linux Virtual Server (LVS), as well as the heartbeat and failover components. LVS is a dynamically-adjusted kernel routing mechanism that provides load balancing, primarily for Web and FTP servers.

Bug Fixes

Previously, the lvsd daemon did not correctly identify the existence of a new virtual server when re-reading the configuration file. As a consequence, the lvsd daemon could terminate unexpectedly with a segmentation fault when the pulse service was reloaded. With this update, the lvsd daemon correctly determines if a virtual server has been added to the configuration file when the pulse service is reloaded.
Previously, the lvsd daemon exited if a nanny process encountered an error as a result of executing the ipvsadm command to add or remove a real server. If a nanny process attempted to delete a real server that was not defined for a virtual service, or if a nanny process attempted to add a real server that was already defined for a virtual service, nanny encountered an error from ipvsadm and exited abnormally. With this update, a nanny process does not exit if it fails to add or remove a real server.
All users of piranha are advised to upgrade to these updated packages, which fix these bugs.
