[m0rgulvale]

Hi All,

My site is http://laserpointerforums.com.



i got some weird errors today... any ideas what is wrong? should i do DB repair function or is this not a big deal?

First Error:

Database error in vBulletin :

mysql_connect() [<a href='function.mysql-connect'>function.mysql-connect</a>]: Too many connections
/home/laserpoi/public_html/laser_pointer_forums_3/forum/includes/class_core.php on line 311

MySQL Error :

IP Address : x.x.x.x

Classname : vB_Database
MySQL Version : 



After that i got more errors like this:


Database error in vBulletin 3.8.2:

Invalid SQL:
SELECT COUNT(DISTINCT(userid)) AS count FROM session WHERE session.userid>0 AND session.lastactivity>1241223334;

MySQL Error : Out of memory (Needed 1048548 bytes)

Is the problem related to these settings possibly?


PHP Max Post Size 80.00 MB
PHP Maximum Upload Size 40.00 MB
PHP Memory Limit 256.00 MB

MySQL Packet Size 36.00 MB


Please advise. should i run any specific DB functions to verify integrity of data? should i change these settings above? if so what would u recommend for my site? i think i have 16mb attachments allowed.

Contact your host.

MySQL Error : Out of memory (Needed 1048548 bytes)

This is the key thing here that was causing things to go boom.
What this is saying is that something, somewhere is using up too much memory, you don't have enough, or something along those lines.

If you're on a shared host, contact your host and have them find out what the problem is. Maybe they've put some unusual memory restrictions on your account, maybe something else entirely.

If you're on a ded server, you've got three options:
A> Find out what's killing your memory and kill the application.
B> Upgrade memory (not going to work if something is hogging all your memory, it'll just keep disapearing)
C> Hire a server manager to handle these kinds of things for you.
