Looking at the code:

    161     protected function load($field = 'id') {
    162         $this->info(sprintf(_('Loading data to field %s'),$field));
    163         try {
    164             if (!$this->get($field)) throw new Exception(sprintf(_('Operation Field not set: %s'),$field));
    165             list($join, $where) = $this->buildQuery();
    166             array_map(function(&$key) use ($join,$where) {
    167                 $key = $this->key($key);
    168                 if (!is_array($this->get($key))) {
    169                     $query = sprintf($this->loadQueryTemplateSingle,
    170                         $this->databaseTable,
    171                         $join,
    172                         $this->databaseFields[$key],
    173                         self::$DB->sanitize($this->get($key)),
    174                         count($where) ? ' AND '.implode(' AND ',$where) : ''
    175                     );
    176                 } else {
    177                     $fields = $this->get($key);
    178                     $fieldData = array();
    179                     array_map(function(&$fieldValue) use ($key,&$fieldData) {
    180                         $fieldData[] = sprintf("`%s`.`%s`='%s'",$this->databaseTable,$this->databaseFields[$key],self::$DB->sanitize($fieldValue));
    181                         unset($fieldValue,$key);
    182                     },(array)$fields);
    183                     $query = sprintf($this->loadQueryTemplateMultiple,
    184                         $this->databaseTable,
    185                         $join,
    186                         implode(' OR ', $fieldData),
    187                         count($where) ? ' AND '.implode(' AND ',$where) : ''
    188                     );
    189                 }
    190                 if (!($vals = self::$DB->query($query)->fetch('','fetch_all')->get())) throw new Exception(self::$DB->sqlerror());
    191                 $vals = @array_shift($vals);
    192                 $this->setQuery($vals);
    193                 unset($vals,$key,$join,$where);
    194             },(array)$field);
    195         } catch (Exception $e) {
    196             $this->debug(_('Load failed: %s'),array($e->getMessage()));
    197         }
    198         return $this;
    199     }

This seems relevant: http://stackoverflow.com/a/5523561/836995 I don’t think you will get a more detailed error message using array_map(). I don’t have time to debug the code, but I can take a guess that this is happening: throw new Exception(self::$DB->sqlerror());

Don’t know why, though.

Output of that link is attached:

I did not expect to see HTML… Parsing the HTML renders this beauty of an error message:

I tried to scan all PCs on my system for viruses by performing the “Virus Scan” task on a group containing all of my hosts. After specifying the task, the PCs rebooted as they should, but got stuck in a “Chainloading failed…”-loop. Cancelling the tasks had no effect. I also tried these instructions: http://www.thelazysysadmin.net/2011/01/fog-deleting-all-current-active-tasks/ The PCs still do not boot.

Running FOG 6909.

Sounds risky, but I’ll try when I have time.

Are you sure?

Thanks for the quick reply.
There were 5 hosts that did not even start, of which two were not even checked in. Yet the multicast started. I’m just confused about the mechanics of that. Is there a timeout, after which the multicast becomes impatient and drops the clients who do not check in, or do not accept data at all?

dolf · Feb 1, 2016, 1:23 PM

Using FOG 1.2.0, I tried to image 13 hosts with a single multicast task. They all finished at slightly different times. I thought that multicast tasks always go at the speed of the slowest client. See attached screenshot:

How is this possible?
