Description jeastmond 1999-10-17 14:58:52 UTC
Intel RedHat 6.0, kernel 2.2.12-10

If I run the following program it creates 240 child
processes and then hangs. If I do ps -ef I get 240 entries
like this:

je        5562  5470  0 15:52 pts/1    00:00:00 [a.out
<defunct>]


It looks like the children aren't being cleared up
properly when they die.

John Eastmond

---------------------------

#include <stdio.h>
#include <unistd.h>

int main(int argc, char *argv[])
{
    int i,ch_pid;

    for (i=0; i<1000; i++)
        {
            if (!(ch_pid=fork()))
                break;
            sleep(1);
        }

    if (!ch_pid)
        {
            int pid=getpid();
            printf("child: %d pid: %d\n",i,pid);
            exit(0);
        }
    else
        {
            int pid=getpid();
            printf("parent: %d\n",pid);
            exit(0);
        }
}

Comment 1 Cristian Gafton 1999-10-17 16:23:59 UTC
You need to wait() for the child process in the parent.
