Hi,
I'm struggling to write a simple forking server. What I have works but
eventually crashes with the following messages:
Error in connection
9130:error:02008018:system library:accept:Too many open files:b_sock.c:735:
9130:error:20065064:BIO routines:BIO_accept:accept error:b_sock.c:736:
Here is an abridged code snippet:
8<----------------------------------------------------------------------------------------------------------------------
sbio = BIO_push(bbio, sbio);
acpt=BIO_new_accept("4433");
BIO_set_accept_bios(acpt,sbio);
/* Setup accept BIO */
if(BIO_do_accept(acpt) <= 0) {
return 0;
}
/* Now wait for incoming connection */
while(1) {
if(BIO_do_accept(acpt) <= 0) {
return 0;
}
sbio = BIO_pop(acpt);
pid = fork ();
if (pid == 0) { // child process (works fine)
if(BIO_do_handshake(sbio) <= 0) {
return 0;
}
BIO_puts(sbio, "Hello\r\n");
BIO_flush(sbio);
BIO_free_all(sbio);
exit (0);
} else { // parent process (eventually crashes after
many connections)
// <----------------- What must I do here, if anything to
free memory, etc ?
}
}
BIO_free_all(acpt);
8<----------------------------------------------------------------------------------------------------------------------
I have a simple client to connect to it, but if I connect enough times,
the server code (above) eventually crashes with the errors shown above.
I think that the problem is that after it forks, the parent process
should release some resource, but I don't understand the BIO_* interface
well enough to know what to do.
I would really appreciate any help, as I'm totally stuck here.
Many thanks,
Thomas
