V. 1.8.7 nullvalue errors

Hello,
I have a production server, which I upgrade since previous 1.8.4 to 1.8.7, running with a2billing current v. 1.9.4, under Centos 5x, where I’m running asterisk in realtime.

I’m having the following error in the Cli, meanwhile calls are progressing correctly, and it’s not affecting the production at all, but it still printing this error:

As I raad around, about the new nullvalue and autoclear directive in app_mysql.conf, I let them as the are in default:

[quote]nullvalue = nullstring
autoclear=yes[/quote]

But I still getting the same error, I tried to change it to nullstring, and emptystring, but no way, it still printing the same error…
I have been updated the a2billing DB as:

ALTER TABLE `cc_sip_buddies` CHANGE `lastms` `lastms` INT( 11 ) NOT NULL; ALTER TABLE `cc_sip_buddies` CHANGE `canreinvite` `canreinvite` VARCHAR( 20 ) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL DEFAULT 'YES'; ALTER TABLE `cc_sip_buddies` CHANGE `setvar` `setvar` VARCHAR( 200 ) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL;

But absolutely no change, neither any progress, asterisk still printing the same error…

Help please!! Cause the message, even it’s not affecting the server production, but it’s not a notice, neither Warring, it’s an error, so I cannot ignore it, or I’m wrong?
