All users of net-snmp are advised to upgrade to these updated packages, which resolve this issue.
1.151.3. RHBA-2009:1372: enhancement and bug fix update
Updated net-snmp packages that fix various bugs and add enhancements are now available.
The Simple Network Management Protocol (SNMP) is a protocol used for network management.
The net-snmp packages include various SNMP tools: an extensible agent; an SNMP library; tools for
requesting or setting information from SNMP agents; tools for generating and handling SNMP traps; a
version of the netstat command which uses SNMP; and a Tk/Perl MIB browser.
These updated net-snmp packages provide fixes for the following bugs:
• using "snmpwalk" to walk a host with automounted NFS mounts sometimes resulted in the snmpd
server timing out if the NFS mount became unresponsive. This update provides a new directive for
the snmpd.conf configuration file, "skipNFSInHostResources", which allows snmpwalk to skip over
automounted NFS mounts when performing a walk. (

)
• the snmp daemon did not correctly report the speeds of network interfaces when they were greater
than 4 Gbit/s. With this update, the actual speed of 10-Gigabit Ethernet (10GbE) network cards are
accurately reported. (
BZ#464061
1251
)
• the snmpd daemon no longer prints spurious "error on subcontainer '' insert (-1)" messages
to snmpd.log when it reloads its configuration file (such as when the daemon is restarted).
(
BZ#468147
1252
)
• the snmpd daemon no longer reports the following errors to syslog when walking through
diskIOTable: "diskio.c: don't know how to handle [x] request". (
BZ#474093
1253
)
• the net-snmp packages were upgraded to upstream version 5.3.2.2 for Red Hat Enterprise Linux
5.3. This update changed the format for the snmpd daemon's "-LS [level] [facility]" logging options
by removing the required space from between the [level] and [facility] arguments. These updated
packages now support both the old-style "-LS" option formatting (space between arguments) and
the new-style (space-less) formatting. (
BZ#477768
1254
)
• the snmpd daemon contained several memory leaks which occurred when accessing the Stream
Control Transmission Protocol Management Information Base (SCTP-MIB). These memory leaks
have been fixed with these updated packages. (
BZ#497280
1255
)
• the net-snmp-devel package contained an undeclared dependency on the lm_sensors-devel
package, which has been made explicit with this update. (
BZ#437819
1256
)
In addition, the following new Object IDs (OIDs) have been implemented in the snmpd daemon:
• RMON-MIB::etherStatsJabbers and ETHERLIKE-MIB:dot3StatsTable. The implementation of
these OIDs is limited to systems with a Broadcom BCM 5708 Gigabit Ethernet Controller or an Intel
Corporation 82541GI Gigabit Ethernet Controller. (
BZ#468832
1257
)
• IP-MIB::ipAddressSpinLock, which allows the synchronization of ipTable modifications.
