This bug has been copied from bug #829271 and has been proposed to be backported to 6.3 z-stream (EUS).
Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: Prior to this update, there was a limit of 50 'exec' entries in /etc/snmp/snmpd.conf. With more than 50 such entries in the configuration file, snmpd reported "Error: No further UCD-compatible entries" in the system log. In this update this fixed limit is removed and there can be any number of 'exec' entries in the snmpd configuration file.
I have encountered some differences between snmpd on RHEL5 and RHEL6... net-snmp-5.3.2.2-18.el5: UCD-SNMP-MIB::extCommand.1 = STRING: /bin/echo message 1 UCD-SNMP-MIB::extErrFix.1 = INTEGER: 0 net-snmp-5.5-41.el6_3.1: UCD-SNMP-MIB::extCommand.1 = STRING: /bin/echo UCD-SNMP-MIB::extErrFix.1 = INTEGER: noError(0) Is this intentional?

UCD-SNMP-MIB::extErrFix.1 = noError(0) is intentional, it just adds meaning to the zero value. UCD-SNMP-MIB::extCommand.1 = STRING: /bin/echo missing cmdline arguments seems to be bug, UCD-SNMP-MIB describes 'extCommand' as 'The command line to be executed,' which IMHO should contain also its arguments.
