Memory LEAK???

[Cold Steel]

Just got this from my host...

I was checking your
error_log file and noticed that you have been receiving numerous 'Out of
memory!' errors. Many of your scripts are failing for this reason.
One of your scripts may have memory leak. Here is a listing from TOP.
Notice that you currently have 137Megs of active memory.

Can anyone help me make sense of that?

One of your scripts may have memory leak.

It is almost unheard of for a PHP or mysql program to have a memory leak. I believe both contain software to contain a memory leak if there is one.

What you might be experiencing is 'not enough memory'. What are the stats of your webserver and how many visitors per day to your forum do you get ? What version of vBulletin are you running ?

It does not appear that the info listed is showing anything that should lead you to out of memory errors, or anything out of the ordinary.

So it would be nice to see the server specs, and how many people are on that server. :)

werehere,

Just curious... have you had any experience with changing the pconnect's to connect and its effects on memory?

It's a dedicated server.

I'm not sure how many people per day are on my forum. It's located at http://aforums.com, if you can take a look for me.

Thanks!

Do you have access to your log files ?

[Cold Steel]

Yes, I do.

Could you run your log files through analog / webalizer / weblog or any other log-file-analyzer to get a rough estimate as to the traffic your board is experiencing ?

There might be a problem is you have 50 people/day visiting your forum. If you have 10,000 people/day visiting your forum, then I'd say your server hardware would need upgrading or more memory.
