RHBA-2009:0095 - Bug Fix Advisory

Topic

An updated piranha package that fixes several bugs and adds enhancements is
now available.

Description

Piranha provides high-availability and load balancing services for Red Hat
Enterprise Linux. It includes 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.

This updated package fixes the following bugs:

• Nanny blocked SIGALRM, causing tftp client timeouts to not be handled.
• Pulse could not be restarted correctly if child processes from a previous

instance of pulse still existed. This occurred to a socket not being closed.

• Improperly handled error case could cause an incorrect log message.
• Pulse could crash if a log message was longer than 80 characters.
• Pulse does not correctly monitor links on bonded interfaces.

Also, this updated package adds the following features:

• Use of an alternate server to handle requests if all real servers are down.
• The pulse init script now reads /etc/sysconfig/pulse on startup, allowing

administrators to override pulse command line options.

Users of piranha are advised to upgrade to this updated package, which
resolves these issues and adds these enhancements.
