XF 1.1 Problem sending mass email

Hi there, I am having a problem sending a mass email, I did a search and found a thread on here of someone else who was having the same problem and the reply suggested that the mysql may have been exceeded and to speak to hosting about increasing the following


I have been onto my hosting and they have told me that they have increased them to

max_allowed_packet = 10M

However I am still getting the same error when attempting to send the mass email.

I am wondering if this is enough to increase it to or should it be more?

The error I am getting when sending the mass email is

An exception occurred: Mysqli prepare error: MySQL server has gone away in /home/chataddi/public_html/library/Zend/Db/Statement/Mysqli.php on line 77
Zend_Db_Statement_Mysqli->_prepare() in Zend/Db/Statement.php at line 115

Thanks in advance.
Thank you :)

Is there any rough idea of how high those settings should be or is it a case of change the settings until the problem goes?

They changed to the defaults and all seems to be working fine now :) managed to send a mass email with no errors and emails seem to have gone through :)
