Hi

I am getting the following error

A fatal error has occured:

Can't call method "fetchrow_hashref" on an undefined value at Links::Build::build_home line 13.

What is odd is if I run an SQL restart command everything will go back to normal.. BUt in about 12 hours it will appear again..

Can you set 'debug' to 2, and then try to recreate this error? There should be a section that specifically deals with the MySQL Command, i.e "SELECT * FROM" ... could you paste that section, so we can see what is actually causing the problem?

I am not sure BUT could it be the following global?
It is the only one with the code $hash in it..

sub {
my ($output,$sth,$hash,$cond);
my $catid = $_[0];
my $limit = $_[1] || 4;
my $search_db = $DB->table(\'Links\',\'CatLinks\');
$search_db->select_options ("ORDER BY rand()", "LIMIT $limit");
my $all_ids = $DB->table(\'Category\')->children($catid);
push @$all_ids, $catid;
$cond = GT::SQL::Condition->new(\'isValidated\',\'=\',\'Yes\', \'CategoryID\', \'IN\', $all_ids);
$sth = $search_db->select ($cond);
while ($hash = $sth->fetchrow_hashref) {
$output .= Links::SiteHTML::display (\'link_short\', $hash);
}
return $output;
}

>>>(\'Links\',\'CatLinks\'); <<<

Are those quotes escaped on the actual global itself? Or did you just grab that from globals.txt?

That was a Global.txt copy

The real global code is:
sub {
my ($output,$sth,$hash,$cond);
my $catid = $_[0];
my $limit = $_[1] || 4;
my $search_db = $DB->table('Links','CatLinks');
$search_db->select_options ("ORDER BY rand()", "LIMIT $limit");
my $all_ids = $DB->table('Category')->children($catid);
push @$all_ids, $catid;
$cond = GT::SQL::Condition->new('isValidated','=','Yes', 'CategoryID', 'IN', $all_ids);
$sth = $search_db->select ($cond);
while ($hash = $sth->fetchrow_hashref) {
$output .= Links::SiteHTML::display ('link_short', $hash);
}
return $output;
}

Try adding an

if ($search_db->hits) { }

around that and see if it makes a difference, or change that line to a print statement like

$output .= "Was this the problem area after all??";

And see if the errors go away.

Missed that.

the 'sock' error means you'll have to restart Mysql, see if that works, if not, you'll probably need root access to fix it up.

Search here on "mysql' and 'sock' for some old discussions on what is going on, and how to deal with it -- old stuff, over 2 years, maybe 3 years or more.

There were a variety of answers for different platforms. I know when I got it, on my Solaris server, I had to reinstall mysql, update a few utilities, and reboot the server then restart MySQL. Of course, your milage will vary, and _hopefully_ a MySQL restart is all that is needed.

Thanks for the input

I have been restaring SQL everytime this happens..
BUT it is happenning again and again..

The admin saying that the MySQL is not the problem but rather something I am running that is causing it to fail..
NO CLUE!

Hi

We just figured it out.. I think

A cron job that was set up using the Cron manager plug in was corrupted..
There was a mistype on the url of the job:

editor_update_de
verses editor_update_def

So every night the cron job starting and is unable to find the sub and is overloading the SQL database and crashing it..

I tried to modify the cron using the manager BUT it will not let me modify or delete the job:

A fatal error has occured:

Invalid Request: 'editor_update_de' '' at admin.cgi line 65.

I tried editing the cron.txt file but it is being overwritten everytime back to the old way..
Anyone has any idea on how to manually edit or delete that cron job?

Hi. If you are still having this problem tomorrow, please send over LSQL admin panel details, and I'll take a look. I'm just going for the night now, otherwise I would have taken a look :(
