Help with MySQL server message...

[kellyandmike]

My forum is 3.5.4 on ipowerweb. When I moved to a new server about 3-4 months ago, (thanks to Heather from this site!) the board ran fine.

Now, members are getting error messages like "cannot connect to page" and here is the error I get sent to my email: (edited to say that the error is not ALL the time, just say 50% of the time)... My members are leaving left and right).

Database error in vBulletin 3.5.4:

Invalid SQL:

UPDATE datastore SET
data = data - 1,
data = IF(data < 0, 0, data)
WHERE title = 'mailqueue';

MySQL Error : MySQL server has gone away
Error Number : 2006

Can someone help me fix this? I am holding for ipower as we speak, but they are experiencing "high call volume" WONDER WHY!!!

hi,

read this (http://www.vbulletin.com/forum/showthread.php?t=43505) this is a known error message

this (http://www.mysql.com/doc/G/o/Gone_away.html) may also become helpfull

[kellyandmike]

Oh my Gosh, that is SOOOO over my head. Can you help me determine which reason it is or at least which query to run to find out? I know how to run queries on mySql

hi,

best you could do is to get in touch with your host as you will be unable to correct this error if you are on a shared host.If you have a dedicated server you could try to edit the MySQL configuration file (/etc/my.cnf) or (my.ini on windows) and that might help.I don't know ipowerweb never dealed with them but it looks like there MySQL is crappy

see Lost connection to MySQL server during query (http://www.vbulletin.com/docs/html/troubleshoot_mysql_goneaway)

Well, much to my dismay, ipower tech didn't seem to know what to do. I think a 10 yr old would have known more. I sent an email to support, so we will see if they help. This is completely frustrating. And, I am NOT on a dedicated server.

When this error comes up is it usually the same? Based on the SQL being executed, it looks like vB is doing something with the mail queue. Perhaps the connection is being closed because sending mail is taking too long? You may want to try disable mail features (under "Email Options") or try reducing the number of emails sent in a batch.

That is, of course, a wild guess, but it might be worth trying.

Farcaster,
It seems to have worked somewhat. I still get the error but not as much. I will post tomorrow AM when my members respond if it is better for them.

In the ACP goto Maintenance > Diagnostics and run the System Information for MySQL variables. Right at the bottom you will find wait_timeout, what is it set to ?

i presume the wait_timeout value is in seconds...
