    WCF System.InsufficientMemoryException

    Getting this error when calling my WCF service. The service is streaming a 150mb file. It usually works the first time I call it, even the second, then I start getting the error.

    error message : Failed to allocate a managed memory buffer of 268435456 bytes. The amount of available memory may be low.

    I don't event know exactly where that number (268435456) comes from. Here is my config.

    Code:
    <?xml version="1.0"?>
    <configuration>
        <system.serviceModel>
          <client>
            <endpoint address="http://localhost:53761/StreamService.svc"
              binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IStreamService"
              contract="StreamService.IStreamService" name="BasicHttpBinding_IStreamService" />
            <endpoint address="http://localhost:53761/ProgressService.svc"

              contract="ProgressService.IProgressService" name="BasicHttpBinding_IProgressService" />
          </client>

                </security>
              </binding>
            </basicHttpBinding>

    Searched on google but found mostly nothing
    Thanks for any help.
