AJAX ScriptManager Memory Leak

[=?Utf-8?B?Tmlrb2xheSBFdnNlZXY=?=]

Hi!

I know this topic has been discussed a long way, but I haven't found any
apparent solution (maybe I shouldn't be looking for a one :)) I have a very
simple application with one page and with just ScriptManager object in it.
Every time I refresh the page the memory usage goes up. I have AJAX
extenstions 1.0 installed and IE7 on winxp. Is this IE or AJAX problem, and
how did you guys cope with this problem?

Please reply asap... i am in emergency

Thanks

I would not panic about memory usage until you know what is happening. By
default, .NET uses memory until it needs it. While this seems like an issue,
it is actually more efficient to leave memory in use than to clear it
immediately after use. As long as the application does not exhibit issues
under load, I would not panic (consider downloading something like the Web
Application Stress Tool - free from MS).

Memory is eventually "garbage collected", but it waits until it needs
memory.

The problem is with my client who is requiring this issue to be fixed asap.
And it does prove to be an issue since the end user may have the same page
opened for days without closing it. All users connect to this application via
citrix (just the way they work, I can't force them to change) and therefore
the memory usage issue becomes crucial.
I've read on some forums that this is due to AJAX not disposing off it's own
objects properly.
But why this works fine on some machines and doesn't on the others. Is it to
do with the fact that older machines have traces of previous ajax versions?

He was talking about JavaScript memory leaks not server side.

Hi,
Try to use a few small update panels instead of single large one if
your program logic allows it. It can slightly soften problem.

This is not particular AJAX problem, it is common IE problem. It is
not designed to work without refreshing page for days.

The page that the client is having the problem with contains only one
updatepanel with a gridview in it.

One more thing - when you minimize the IE window, memory goes back to normal

Nice solution. Add this to the program manual :)

We are seriously considering this :)
