No buffer space available. (Error 10055)

An operation on a socket or pipe was not performed because the system lacked sufficient buffer space or because a queue was full.

This error indicates a shortage of resources on your system. It can occur if you're trying to run too many applications (of any kind) simultaneously on your machine. If this tends to occur after running certain applications for a while, it might be a symptom of an application that doesn't return system resources (like memory) properly. It may also indicate you are not closing the applications properly. If it persists, exit Windows or reboot your machine to remedy the problem. You can monitor available memory with Program Manager's "Help/About..." command.
