Description Rupesh Patel 2019-06-11 14:51:23 UTC 
+++ This bug was initially created as a clone of Bug #1719350 +++

The current version of net-snmp (net-snmp-5.8-7.el8.x86_64) flood messages file with following messages on the system having ipv6 disabled.

 ipaddress_linux: could not open /proc/net/if_inet6: No such file or directory

Upstream has already fixed this bug by just writing this line once instead of so many times.

Subject: [PATCH] MIB-II: Only log once that opening /proc/net/if_inet6 failed

If IPv6 has been disabled (ipv6.disable=1) then opening /proc/net/if_inet6
fails. Only log this once instead of thousand of times a day.
