fork() in for loop
hello,

Every time i use fork() in the for loop, my college network(which i work in) either gets slow or hangs up.Can any 1 explain why it is so?

Of course there is no use of doing it though. But still i want to clear my doubt.

Thanks

NAME

       lo - software loopback network interface

SYNOPSIS

       /sys/conf/SYSTEM:
	    NLOOP     1    # loop-back pseudo-device

DESCRIPTION

       The  loop  interface is a software loopback mechanism which may be used for performance analysis, software testing, and/or local communica-
       tion.  As with other network interfaces, the loopback interface must have network addresses assigned for each address family with which	it
       is to be used.  These addresses may be set or changed with the SIOCSIFADDR ioctl.  The loopback interface should be the last interface con-
       figured, as protocols may use the order of configuration as an indication of priority.  The  loopback  should  never  be  configured  first
       unless no hardware interfaces exist.

DIAGNOSTICS

       lo%d:  can't  handle  af%d.   The  interface  was handed a message with addresses formatted in an unsuitable address family; the packet was
       dropped.

SEE ALSO

       intro(4N), inet(4F), ns(4F)

BUGS

       Previous versions of the system enabled the loopback interface automatically, using a nonstandard Internet address (127.1).   Use  of  that
       address is now discouraged; a reserved host address for the local network should be used instead.
