#96 Can't access system database

[Anonymous]

Hi,
I got the following error, when I try to access system
database!

Error - Perl execution failed

Can't use an undefined value as a HASH reference at
/usr/lib/perl5/DBD/mysql.pm line 113.

bye,
Christian

Same bug here. Someone knows a solution?

I found a solution using Google. Enter in the config of the
nagmin module and disable the use of dbi. We should wait for
a new nagmin version without this bug for enable it.

The solution's given over at http://lists.mysql.com/perl/2570

You need to add

$attrhash ||= {};

before line 112 in mysql.pm

This bug's present in versions 2.9003 and 2.9004 AFAIK, and
maybe more.

I've logged a bug report against DBD::MySQL here:

Verified fixed with the suggested one line change.
