1.86.1. RHBA-2010:0422: bug fix update
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.
* snmpd, the SNMP daemon, could have leaked file descriptors periodically when retrieving data for RMON-MIB. This leak could have exhausted file descriptors for the snmpd process and rendered the daemon unable to respond to SNMP requests. With this update, all unnecessary file descriptors are appropriately closed so that snmpd thus no longer leaks file descriptors. ( BZ#585202
All users of net-snmp are advised to upgrade to these updated packages, which resolve this issue.
