Erro funçao unserialize

Estou com o seguinte erro

Notice: unserialize() [function.unserialize]: Error at offset 840 of 2302 bytes in /data/methods/mob_db/ver-MonsterController.php on line 329

a linha e

$Spawns = unserialize($this->getAttr('spawns'));

Ou seja

if(is_array($Spawns)) {

 $pASD="";

 foreach($Spawns as $cS => $sP) {

 $mname = $cS;
 $title = $sP['map_name'];
 $count = $sP['amount'];

 if($count==FALSE) continue;
 else $pASD .= "<li><a href=\"?act=ver-mapas&field={$mname}\">{$title}</a> ({$mname}) [{$count}]</li>";

 }

 $Spawns = substr($pASD,0,-2);

 }

 if(!is_string($Spawns) || strlen($Spawns)==0) $Spawns = "<center>N/A</center>";

 $this->setAttr('spawns', $Spawns);

 // Monster drops

 $this->setAttr('drops', $this->createItemDropTable($this->getAttr('drops'),1));

 // Boss drops

 if($this->getAttr('mexp') > 0) {
 $this->setAttr('mdrops', $this->createItemDropTable($this->getAttr('mdrops'),2));
 }

 }

essa funçao fais exibir os mapas que aquele mob vive de acordo com a tabela na mysql
