<p>Is there a connection limit on Sql Server 2005 Developers Edition.  We have many threads grabbing connections, and I know ADO.NET does connection pooling, but I get OutOfMemory exceptions.  We take out the db connections and it works fine. </p>

You may not be closing or disposing of your connection objects correctly.  Make sure your code looks something like this:
```
```
using (SqlConnection conn = new SqlConnection("connectionstring"))
{
    conn.Open();

    // database access code goes here
}
```
```
The using block will automatically close and dispose of your connection object.
