I tried to submit a Poll as a test user and got this back. I have run into this several times. Have any idea what can cause this?

Sutharsan CreditAttribution: Sutharsan commentedPerhaps this MySQL page can help you: http://dev.mysql.com/doc/refman/5.0/en/gone-away.html
Otherwise I suggest you contact your web host.
Comment #2
Kat_Sweden CreditAttribution: Kat_Sweden commentedI encountered a similar problem adding content types. Increasing the maximum allowed packet size for MySQL should fix this:
- Go to .../mysql/bin
- Open "my" or "my.cnf"
- Set max_allowed_packet=64M (or something larger than your current setting depending on your server hardware)
- Restart MySQL
What happens is if the MySQL server receives a packet bigger than the size in the config file, it throws an error and closes the connection. PHP then displays the "MySQL server has gone away..".
You can read more about this config setting here:
http://dev.mysql.com/doc/refman/5.0/en/packet-too-large.html

trunksye CreditAttribution: trunksye commentedI suggest anyone with this problem should first check with your webhost about wait_timeout setting for mysql. My webhost set it to 3 seconds at first! Now they have changed it to 8 seconds and my little drupal is ok!even with update status on!
Comment #6
g76 CreditAttribution: g76 commentedthis worked for me. I am on a shared hosting account, no access to mysql settings, but this seemed to fix it:
http://drupal.org/node/227445#comment-770663
also, disable syslog and database logging.
