Error in Notes client: 'The TCP/IP protocol stack reported that it ran out of memory'
The following message text appears in a dialog box on a Lotus Notes client:
"The TCP/IP protocol stack reported that it ran out of memory. Consult your network documentation to increase configured memory, or reduce Notes connections by limiting clients (see SERVER_MAXSESSIONS parameter in Notes Admin Guide)."
The text of this message can be somewhat misleading when the error occurs on the Notes client. Generally, the problem is that the client operating system and network driver have a problem with resources; the problem does not lie with the Lotus Domino server that the client may be connected to or is attempting to connect to. (Note: This error can also appear on a Domino server console output; in that case, the problem would lie with the Domino server. Domino server administators can refer to the Administrator Help for troubleshooting information.)
When this error occurs on a Lotus Notes client, no changes to the Domino server are necessary. Restarting the client machine will resolve a one-time occurrence. Persistent errors on an individual workstation might require further troubleshooting.
Some troubleshooting techniques to try include the following:
- Run a virus scan on the PC. A worm or virus attach can send tremendous amounts of requests using TCP/IP, affecting the protocol stack.
- Increase the page file size or virtual memory for Microsoft Windows. The following Microsoft technical articles discuss how to adjust these settings:
#307886, How To Move the Paging File in Windows XP
#308417, How to set performance options in Windows XP
These articles are available at Microsoft's Support site at
- Update the network drivers.
- Reinstall the TCP/IP driver.
- Check your firewall settings. Try an uninstall and reinstall of the firewall.
- As a last option, you can reinstall the Notes client.
