+Subject: IP-MIB, Linux: Fix a memory leak in an error path
+
+When a Linux system is booted with "ipv6.disable=1" in the kernel command
+line, the file "/proc/net/snmp6" is not created. Fix the memory leak in
+_systemstats_v6_load_systemstats() that is triggered with IPv6 disabled.
+
+See also https://sourceforge.net/p/net-snmp/bugs/2976/.
+
+Reported-by: Mark E Rusk <marker55@users.sourceforge.net>
