Out of memory exception error

[melbert2002]

Hello all,
Here is the situation. I have a W2K3 web server running IIS 6.0 connecting to a SQL server 2005 box. Every once in a while I will get a Out of Memory exception error (please see below) that takes down all my sites for about 20 min until it clears up. Has anyone ever seen this? I am not a developer just a system admin.

Thanks in advance

Mel

oh yes...i have seen this error lot of times...

instead of waiting for 20 mins...you can kill the process called aspnet_wp.exe

-DNG

For a little added protection (not much), if your Server has 3GB or more of ram you can use the "/3GB" switch on your servers boot.ini file.

If you know nothing about this switch, normally the OS will allocate half of all ram for it's own use and leave the other half for applications and services like IIS and SQL... but with this switch the OS will be limited to 1GB of memory for its own use and leaves the remaining ram for applications.

Note: If you have less than 3GB of ram, this switch is useless.

Thanks for the info, but here but the issue is that these are live servers for my websites and I cant keep on having my sites die.

Could it be the way that ASP is connecting to the DB?

Thanks
