aspnet_wp.exe memory problem

[EDom]

Hi,

I have aspnet_wp.exe with increasing on every postback and not every revisit
to any page. Even if I clear session and close the browser it remains in the
memory. I have only one connection object and it is closed always as I have
it under try catch, and all my variables are disposed at the end of each
function. What could be the issue??

This is normal behaviour, unless it is causing you a problem.
..Net usually grows and grows until garbage collection comes and cleans it
up.

You can force a collection with the GC.Collect() Method. But you should not
need this most of the time.

GC only fress memory if there are other apps which needs more memory. If
there is enough free space it will not free memory.

I get Server Error : Application cannot accept anymore requests.
I have to go to task manager kill the process and then all is fine.

Not everything in .Net cleans itself up. Are you closing all of your
database connections?

If you really want to know what's going on, you should attach Windbg to the
process, load the SOS extension, and have a look at what's in memory.

# re: When to call GC.Collect()
Monday, November 29, 2004 4:02 PM by Darren Oakey
hmm.... I would disagree...

how about rule1: use GC.collect often and with a vengeance! :)

In my experience, the .net GC is a piece of **** and shouldn't be trusted.
We have found a number of production bugs that have been solved by a single
introduction of GC.Collect.

try it - make any batch routine that say - traverses your disk, opens each
file and computes a checksum, and run it with task manager open - it's quite
an eye-opener. The memory just goes up... and up... and up...

Now, insert the lines GC.Collect(), GC.WaitForPendi ngFinalizers() after
processing each file. Your job will run _quicker_, because the system isn't
continuously allocating memory, and the memory usage of your program will
remain constant.

I would say

rule 1: Use GC.Collect at the end of any major "operation" , or any form
finishing

rule 2: In any loop situation, always follow it with
GC.WaitForPendi ngFinalizers

rule 3: explicitly dispose anything that it's possible to dispose - to a
large extent, pretend the GC doesn't exist, and you are in an old language.
