database error – [Lost connection to MySQL server during query]

At the upgrade, did you follow the upgrade instructions?

o Backed up
o Deleted all files except wp-config.php, .htaccess and the wp-content directory
o Uploaded the new distribution exept the wp-content directory
o Run the upgrade.php script from your browser.

An upgrade may lead to some changes in the database.

I did everything

I have the same issue with WP 2.01 when posting.
This is the error message:
WordPress database error: [Lost connection to MySQL server during query]
INSERT INTO wp_postmeta (post_id,meta_key,meta_value) VALUES (’59’,’_pingme’,’1′)

Warning: Cannot modify header information – headers already sent by (output started at /ainostriamici/wp-includes/wp-db.php:102) in /ainostriamici/wp-admin/post.php on line 59

Anyway the post will be published, but even if I have disabled comments, they will appear the same.
I have again to edit the post a 2°time in order to effectively disable comments in the post.

Hello all,
I have exactly the same message on two differents blogs :

WordPress database error: [Lost connection to MySQL server during query]
SELECT option_value FROM vhd_wp_options WHERE option_name = ‘sm_options’ LIMIT 1

This is 2.01. As soon as I publish a new note, it takes a long time then I get the error message.The post is ok when I come back to the frontpage.

I foolowed the exact upgrade procedure for the both sites.

I found a plugin that helps with the problem of database connection errors when posting. It is the No Ping Wait plugin and since I have been using it I have not had any connection errors. You can get it here:

Just put it in your plugins folder and activate then your all set.

This is the solution I found for this problem.

Sign in to your wp-admin. Go to Options > Writing > Update Services. Delete ALL update services except:
