out of memory
I am using asp.net and vb code behind to build a website with multiple update panels. The purpose of this is the continually update charts in the panels at a frequency of 1 second intervals. The code works fine until it runds for about 17 to 20 minutes. At that point I get an out of memory message from the web page - 'out of memory at line 1301'.
I have tried clearing memory out of cache by using the following in page load:
Cache.Remove("WebForm5.asp
Cache.Remover("Repeater1")
I have tried the above cache removal code for each control and for the page in which I have the update panels. They have no effect at all.
I have also tried setting the 'EnableEventValidation="Fa
Several questions:
1. Is this asp.net code line 1301 or vb code behind?
2. Is cache automatically loaded into memory even though I am not programmatically loading any into cache?
3. Why does the Cache.Removal code have no effect?
What else can I try?
Can anyone help?
Thanks in advance.

Run the web site from IIS. Set the recycling propertes in Application pool to use reserved memory size.
I suspect the problem is 1 second interval. I dont think request goes to the server and comes back within a second. So you essentially create a long queue of AJAX calls and it brings the system down at some point. Try testing with a 5 second interval.
in addition to the above...do a garbage collection and destroy object, varaibles...

yatin 81 - I don't have a 'reserved memory size' option in my Application pool.
CodeCruiser - setting the time interval to 30 seconds did the trick. I have a lot of data feeding 3 charts and 3 gridviews on the same page and the I guess this was the interval that was needed to correct the situation. I do suspect that when I start running the web site from IIS and the production application is installed on the server I won't have the problem to the same extent.
Correct?
