Wrong datatype saving emails

[emmettPower]

Hi,

I am using a template to send short emails. Sending seems to work but when it gets the save part of the process I get the following message:

->
Warning: in_array() [function.in-array]: Wrong datatype for second argument in opt/lampp/htdocs/SugarOS/modules/Emails/Save.php on line 154 Query Failed:INSERT into emails.....::MySQL error 1153: Got a packet bigger than 'max_allowed_packet' bytes".
<-

The email has a 1.4mb pdf attachment.

Any idea what's the problem?

Thanks

Emmett

I should have mentioned that line 154 is:

if(!in_array($_REQUEST['object_id'],$exContactIds)){ <-------------------

$rel = strtolower($_REQUEST['object_type']);

$focus->load_relationship($rel);

$focus->$rel->add($_REQUEST['object_id']);

$GLOBALS['log']->debug("CESELY LOADED".$_REQUEST['object_type']);

}
