Database error 2

I'm getting an e-mail saying that has a dababase error in a VERY LONG message, I've been talking to Lynne and he said that the important is the end of the message:

MySQL Error : Got a packet bigger than 'max_allowed_packet' bytes

Look's line that the problem is ALWAYS with the showgroups.php

Any solution for that? Disable that group or whatever?

Thanks.
