Reinstalling vBulletin is not going to do anything. Just look at the output of the top command.

I think you're really trying to help, so I'll post this and hope you don't take it the wrong way.

Your responses are assuming way too much knowledge. "you have too many PHP forks running" describes the result of a problem, but doesn't tell the poor guy what to do about it.

He's at the point now where he'll do anything you say, but now you've got to give him some sort of action to take. What should he do next to try to solve the problem?

No, I mean to make a fresh installation and use IMPEX to transport the forum data on a new board, in order to get rid of all plugins, style changes and eventual errors.

Just backing up and restoring would not help. It would just reproduce the same problems on the new installation ;)

It seems his host is not very cooperative and just tries to guess where the problem lays.

I try to fix the problem without touching the hardware and server settings, since this would require to change host.

There are some errors on style basis which cause the pages not to load correctly and may have side effects on certain scripts. These errors are present with and without plugins. It may also be, some of the plugins are outdated, but I doubt the problem is there.

After he upgraded to 4 GB RAM the problem continued. With permanent connections, the problem was less frequent, which points my finger to the MySQL settings.

I'm not sure if PHP run as CGI makes the big difference, since it should just run shortly an instance of PHP for each client. Of course it would show a long list of instances, if the operating system doesn't unload them quickly. At most there could be a short delay between connections. MySQL errors could occur, if the PHP instances don't unload quick enough while other client connections are incoming. I've no idea how Linux handles CGI, and how applications are scheduled.

PHP run as CGI is the usual way to keep processes apart and avoid to crash or block the whole server if one client instance crashes or blocks. However it is useful only in shared virtual servers.

until now for 2days.im not getting the many error message in my mail.

yesterday my support host ask i must upgrade the ram for fixed my issue.

In order to fix the attachmentviews problem, you can try to add the following line to your config.php and see if this makes any difference:

i put the code in bottom of config.php
but thats not work.
im always get database error :

Well I don't know. My smallest server gets ten's of thousands hits per hour and still doesn't give up. The MySQL gone away error is usually a record size problem, and the server should time out at most = no reply = white or error page. For me it's a server setting issue. But of course, if you are on a shared environment - as it seems -changing the settings may be done only within certain limits.

I don't know if you solve the problems you have now switching to a "professional" solution of the same host. If I was you I'd look to get the best for my money, which isn't necessarily the cheapest. I would buy a good computer, giving the most attention to the hard disk quality, add some RAM, install an operating system, the latest Apache, MySQL and PHP and would go housing after a home test session. This way, you know what you have and if something doesn't work, you know how to fix it. It has a relatively high cost because of the computer, the OS and preliminary work, but pays off after a year, because the expense of housing is very small.

That server should be more then fine for your traffic depending on your site and what add ons you have. If this is just for one vbulletin forum then your server or software configuration is way off.
