FastCGI plugin hangs after exit a process

Question

Hi there again.
I�m developing a FastCGI application on a Sun One 6.1 SP 5 over Solaris 2.9.
I success in launching my FCGI Perl application, and it works fine in almost every case. But I have one issue, in which I make an exit in my program (jumping out the accept loop) , in order to restart my application. Here you are the last lines of perl code...
$request->Finish();
logEvent ("LoginCGI v.2.0: Shutting down");
close LOGGER;
$M_ldaph->unbind;
$R_ldaph->unbind;
exit(1);
So far, so wood. I can issue a ps -ef and no process is running on the system.
The problem is that when the following request comes, FCGI plugin is unable to start a new process of my application,returning a HTTP 500.
In this state, I can see in the machine a socket LISTENING on the port that my application does.
10.20.250.49.25757 *.* 0 0 32768 0 LISTEN
Seems that this port is not closed by the web server, and so NO new connections on this port can be engaged.
Do you know what could be the reason of this behaviour ? I think that this problem is not happening over Windows...
Thank you very much in advance.
Best Regards.

I tried running the following simple perl program and it worked fine for exit(0).
use FCGI;
$cnt = 0;
while (FCGI::accept >= 0) {
print "Content-type: text/html\r\n\r\n";
print "<h1>FastCGI Demo Page (perl)</h1>\n";
$cnt++;
print "This is connection number $cnt\n";
if($cnt > 2)
exit(0);
Are you sure there weren't any old application processes running when you tried testing the modified one ?
Would it be possible for you to do the following ?
1. Shutdown Web Server
2. Check if your perl application process and Fastcgistub process have terminated. If not, terminate them manually.
3. Check if the perl application specified in the obj.conf is the one with exit(0) code.
4. Restart the Web Server and send the request.
Let me know if you still observe the hang.
Thanks,
Seema.
