Memory leaks caused by ASP (VBScript) scripts


Question

I have been working on a server problem on behalf of a client, and the hosting company has decided that the slowdowns the website experiences periodically are due to "a memory leak somewhere in the code of the website." This website is not using any compiled code, so I don't see how it's even possible for the code to have a memory leak. I just want to make sure that I'm correct before I tear these idiots a new a-hole.

Yes it is... if your DB connections and/or other objects are not properly closed at the end of every page execution, it can cause these objects to remain in memory. Remember... ASP does not have "garbage cleanup" like ASP.NET and even ASP.NET can be subject to these things.

And code does not need to be compiled to be loaded into memory... if you remember Computing 101 then you'll remember that before ANYTHING at all executes on any computer it is loaded into memory and run from there. So if these things are not released from system memory they may not always find their way out.

Sure there is... Recordset objects, improperly used arrays, loops that dont exit properly, i mean you keep leaning towards "there's no way" but there's plenty, and much of it can't be pointed out without looking at your code.

Another thing to consider... if you're working with a large DB, ASP has a timeout period where if the page doesn't finish processing before that amount of time the server will terminate the process and when that happens everything doesn't always get closed/discarded correctly.

There is any number of things it could be... instead of leaning toward "it cant be" how about either helping us help you by posting code or really really going thru it yourself. No harm or hurt intended. :)

    • The word "standard" has a very broad set of definitions that covers many uses beyond technical standards. Also, "de facto standard" is a common phrase with its own meaning, which I used correctly.
    • Just want to throw in my two current favorite streaming shows both of which have brilliant theme songs.  Added bonus. Another fun new show is called Duster starring Josh Hollaway. It's opening theme is brilliant.  
    • Depends on where you are from. I know in the US they love their Messages because ISPs there were blocking mobile data for certain apps, especially messengers and voip apps because they wanted to sell bundles of call minutes and sms messages (the reason why Skype was not so popular in US as Microsoft expected - at the very beginning it just couldn't run on mobile data at all in US). Here in EU I don't know anyone using Messages because we moved to better messenger apps long ago. I've used a Java version of ICQ and Google Talk on my dumb phone before the iPhone was a thing.
    • Do we really need to bring more attention to yt-dlp? I'm sure that project will be pulled if it becomes super common knowledge.
    • Windows Photos gets AI-powered light controls and improved search by Taras Buria Microsoft is rolling out a new update for the Windows Photos app in the Insider program. Today's release introduces two new AI-powered features: light controls (Relight) and search with natural language (initially announced in early May 2025). With Relight, users can set up to three light sources on a single image and customize their light color, focus point, brightness, and intensity. The app has built-in presets for quick light adjustments and styles, which you can apply with a single click. Microsoft says that besides styling your photos, Relight can correct poor lighting on images to make them look better. As of right now, Relight is only available to Windows Insiders with Snapdragon-powered Copilot+ PCs. However, Microsoft promises to release the feature to users with AMD and Intel-based Copilot+ PCs in the coming months. Next is improved search, which is now semantically based, allowing you to find photos using natural language. For example, you can search for "sunset at the beach" or "family outdoor fun." Windows Photos will use AI to understand your request and find photos that best fit it. Note that improved search only works with locally stored and indexed pictures in the Pictures library. More information about indexing and supported languages is available in the official documentation. Finally, two Windows Photos features are now available to Entra ID users: Restyle Image and Image Creator. Previously, these features were only available to customers with standard Microsoft Accounts. For reference, Restyle Image lets you use AI to reimagine your photo in a different style, while Image Creator enables you to generate pictures using text prompts. The new features for the Windows Photos app are now rolling out in all Insider channels in version 2025.11060.5006.0 and higher. You can read more about them in the official announcement post.
