Got a packet bigger than 'max_allowed_packet' bytes

Unfortunately, this does not contain enough information to debug this issue. At the very least I need a cut & paste of the full error that it generated, and exactly what you were doing at the time.

The message that it's trying to insert into watchdog woudl probably be helpful too.

I got the same error when I tried to install version 6.x-1.0-beta2:

Warning: Got a packet bigger than 'max_allowed_packet' bytes query: INSERT INTO kraxln_watchdog (uid, type, message, variables, severity, link, location, referer, hostname, timestamp) VALUES (1, 'php', '%message in %file on line %line.', 'a:4:{s:6:\"%error\";s:12:\"user warning\";s:8:\"%message\";s:1729733:\"Got a packet bigger than 'max_allowed_packet' bytes\nquery: UPDATE kraxln_cache_menu SET data = 'a:1030:{s:4:\\"node\\";a:26:{s:5:\\"title\\";s:7:\\"Content\\";s:13:\\"page callback\\";s:17:\\"node_page_default\\";s:16:\\"access arguments\\";a:1:{i:0;s:14:\\"access content\\";}s:4:\\"type\\";i:4;s:6:\\"module\\";s:4:\\"node\\";s:14:\\"load_functions\\";s:0:\\"\\";s:16:\\"to_arg_function in /home/kraxlnat
/public_html/includes/database.mysql.inc on line 128

After disabling the module, the error disappears. Unfortunately I cannot increase the max_allowed_packet variable here, as we're on a shared environment.
I hope that helps!

hubarbeit: That isn't a problem in particular with this module, but with Drupal itself. It caches the menu data, and enough modules can make the menu cache rather large. There's nothing I can do about that.

The following worked for me on Ubuntu 8.04.x LTS desktop edition http://drupal.org/node/541396

This is a fairly common issue with mysql - you need to increase the max_allowed_packet from its default (which is usually 1M). The 'perfect' number depends on your system's configuration, but I personally jack it up pretty high, to 16M.
