This is not an issue with the plugin but with your redis perl library that has not been updated to properly support 2.6. This is the same problem discussed in: https://github.com/willixix/WL-NagiosPlugins/issues/16

Hi,

I was bitten by this issue also and spent some time on it. Maybe it would be more userfriendly to detect this corner case and show some warning instead of an error message which is wrong, missleading and doesn't help at all? :-)

Indeed, installing new version of Redis Perl library fixed it. Thanks.
