Note Submitter: floyd@studiodust.com ---- I discovered that if I popen a C program that forks and execs a daemon, or any program that does not exit, file descriptors that remain open will keep the WEB server from closing the connection or keep it from pening a new connection. I'm not exactly sure what the underlying problem is, but after the popen'ed program exited my browser reported that the document was complete but I got no repsonse when I attmepted to return to the PHP script that spawned the process. The forked process was closing file descriptors 0, 1 and 2, as I had to do when spawing this process form a CGI perl script. But I determined that when spawned from a PHP script there were 2 or 3 additional file descriptors open and I had to close those as well. I determined how many file descriptors to close in the forked process by savig the file descriptor value of the first file my program opened. I am running PHP 4.0.5 with Apache 1.3.19 under Linux 2.2.10.
