Out of memory when having lot of memory!

Hi All,

Our aspnet application is randomly thrown this exception:
System.OutOfMemoryException

It only happens on our bigger 2003 server (4GB of ram!)

I've found this on Microsoft site:
http://support.microsoft.com/kb/820108

This could be our problem but how to be sure ?
To be honest, I'm a bit nervous changing the boot.ini on a remote server.

Has someone already applied this /3GB stuff in boot.ini.

Thanks for any feedback,
Jean-Michel

Read http://www.codeproject.com/showcase/...TSProfiler.asp
for a classic (costly) example as to how handlers can cause leaks.

Hello jmr,

the problem lays in the nature of CLR memory management.
The keyword is that memory MAY be fragmented.
As u may know memory is reserved in blocks 32/64mb, and when your app request
another 10kb, CLR might don't find enough place in fragmented memory to reserve
another block

just to google and u find some mine post where i described this

So you if you want to develop a "non normal" website needing more
memory, you cannot just buy memory and put it into your box because
windows limitations !

Also, about memory leaks, some ASP.NET announces says it should not be a
problem:
ASP.NET ensures that your application is always available to your users.
* Memory Leak, DeadLock and Crash Protection. ASP.NET
automatically detects and recovers from errors like deadlocks and memory
leaks to ensure your application is always available to your users.

I must say I'm a bit disapointed.
