System.OutOfMemoryException

Hi,
We have an application using .NET framework 1.1 and SQL Server 2000. The
application seems to be running very well until we get an OutOfMemory error.
The computer has enough memory, in fact, when the error takes place there
are 2 GB available in physical memory.
Some days ago, we have a limitation in memory for DefaultAppPool of 1,5 GB
before recycling.This made the session information be lost quite often, so,
we decided to increase the limitation to 3GB and then, we got the
OutOfMemory error, although our server has 8GB of physical memory and only
3GB is used by SQL Server. Now we have the Maximum used memory (in
megabytes) to 2100.
Do you have any clue about why we have memory problems when there are 2GB of
physical memory available?
Thank you very much,
Any guidance will be appreciated.A common source of memory problems is not closing database connections.

unless your running 64 bit or 32bit with the 3gb switch, 2gb is the max you
can set the memory to.

Thank you very much for your help. I have the /3GB in our boot.ini file:
[boot loader]
redirect=UseBiosSettings
timeout=30
default=multi(0)disk(0)rdisk(0)partition
(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WIND
OWS="Windows Server 2003, Enterprise
3GB" /fastdetect /3GB /PAE /redirect /NoExecute=OptOut
Are there anything else we can do in order w3wp.exe to be able to use more
than 2 GB?
Thanks a lot.

Are you doing any work like dynamically generating images using GDI?
If so you might want to make sure that the code cleans up after itself
correctly or your server memory will go through the roof!

System.OutOfMemoryException

Hi,

We have an application using .NET framework 1.1 and SQL Server 2000. The
application seems to be running very well until we get an OutOfMemory error.
The computer has enough memory, in fact, when the error takes place there
are 2 GB available in physical memory.
Some days ago, we have a limitation in memory for DefaultAppPool of 1,5 GB
before recycling.This made the session information be lost quite often, so,
we decided to increase the limitation to 3GB and then, we got the
OutOfMemory error, although our server has 8GB of physical memory and only
3GB is used by SQL Server. Now we have the Maximum used memory (in
megabytes) to 2100.
Do you have any clue about why we have memory problems when there are 2GB of
physical memory available?

Thank you very much,
Any guidance will be appreciated.A common source of memory problems is not closing database connections.

System.Security.Cryptography.CryptographicExceptio n:

Hi,

I have two web applications running on my machine.The
application is developed using asp.net 1.1 and vb.net.When i try to run
both the applications in the same browsers, i get the following error.
(System.Security.Cryptography.CryptographicExcepti on: Bad Data. at
System.Security.Cryptography.CryptoAPITransform._D ecryptData(IntPtr
hKey, Byte[] rgb, Int32 ib, Int32 cb, Boolean fDone) at
System.Security.Cryptography.CryptoAPITransform.Tr ansformFinalBlock(Byte[]
inputBuffer, Int32 inputOffset, Int32 inputCount) at
System.Security.Cryptography.CryptoStream.FlushFin alBlock() at
System.Web.Configuration.MachineKey.EncryptOrDecry ptData(Boolean
fEncrypt, Byte[] buf, Byte[] modifier, Int32 start, Int32 length) at
System.Web.Security.FormsAuthentication.Decrypt(St ring
encryptedTicket))

That is, when i run the first application and run the second
application in the same browser, i get this error.If i run it in two
different browsers, then it works fine.

Can any one help me out.r u using Forms authentication?
