Event ID: 4047 Source: TlntSvr

An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full.
According to a Microsoft support enginner, this error can occur if OS is running out of non-paged pool. Are you using the /3GB switch on the machine? Please turn it off and try again.

As we know, using /3GB will cause the OS to have only 1GB memory for system use. The paged pool and non-paged pool size will be half the default size. These memory pools are used by OS to store network buffers, etc. Thus, when /3GB is turned on, it is more likely that OS will run out of non-paged pool and be unable to serve socket calls.

As you are using /PAE, the user application already can use the additional 4GB memory. It is recommended to turn off /3GB so that OS could run more smoothly.
