max_allowed_packet

[indaka]

When I try to load the ITSM- ChangeManagement 2.1.1 I got following error
ERROR: OTRS-CGI-10 Perl: 5.8.8 OS: linux Time: Mon Dec 20 22:51:24 2010

Message: Got a packet bigger than 'max_allowed_packet' bytes, SQL: 'INSERT INTO web_upload_cache (form_id, filename, content_type, content_size, content, create_time_unix, content_id) VALUES (?, ?, ?, ?, ?, ?, ?)'

I could not resolve this by changing the my.cnf with
max_allowed_packet=32M

Please help
