This error normally means that there is no more memory for the sockets in kernel space. This must never happen during a socket() or connect() call, otherwise it indicates that your system is under strong memory contention. Is your system swapping ? Or worse, is it virtualized with memory ballooning or other such horrors^H^H^H^H^H^Hbeauties that make you believe you're running with unlimited resources while in fact you're running with no more resources at all ?
